c802d12a1e emacs/show: Accommodate the lack of part header buttons
Various pieces of code assumed (reasonably) that part header buttons
are present. Modify them to avoid problems if no part headers were
inserted.

92a1f9ba17 emacs/show: Make the insertion of part headers overridable.
This allows callers of notmuch-show-insert-bodypart to use a `let'
binding to override the default function for specifying when part
headers should be inserted.

We also add an option to never show part buttons which will be used by
the test suites for the reply tests.

c689d1ff13 emacs: Report a lack of matches when calling `notmuch-show'.
If the basic query passed to `notmuch-show' generates no results, ring
the bell and inform the user that no messages matched the query rather
than displaying an empty buffer and showing an obscure error.

Similarly when refreshing a `notmuch-show' buffer and no messages match.

bfb7098514 emacs: notmuch-show-view-raw-message clears buffer, makes it read-only
notmuch-show-view-raw-message() re-uses buffer created with same
name (same Message-Id:) but it did not erase it before filling.
If this ever happened, there were duplicated (potentially overlapping)
content in the buffer. Now this is fixed.
Apparently since emacs 24.5 the (view-buffer) makes the buffer read-only;
so this problem would not have happened there, just that
notmuch-show-view-raw-message() failed. This is fixed by setting
inhibit-read-only t before erasing and filling the buffer. The emacs 24.5
feature having raw message buffer read-only is also now explicitly set to
the buffer so the same experience is available with emaces < 24.5.

cbf2448bb1 emacs: Fontify From with message-header-other
Commit e26d767897 changed the
fontification of the body associated with the From header to
message-header-from.  However, that face is non-existent, and in
message.el (message-font-lock-keywords) the From-header falls through
and is attributed the message-header-other face.

This commit removes the fontification of the [Ff]rom header in
notmuch-show-mode in order to fontify it using the message-header-other
face.

This only affects non-default configurations where
notmuch-message-headers is set to display From.

ff1fb5027c emacs: show: increase default max-text-part-size
Currently notmuch-show-max-text-part-size is 10000 which means some
relatively normal messages have all parts hidden by default. Increase
this to 100000 by default.

The setting was introduced to alleviate problems with notmuch being
very slow on large threads. Users hitting these problems may wish to
customize this variable to something smaller (like 10000).

Note that it is not the same as filter in search mode as it replaces
the existing query rather than ANDing with it (but it does keep the
thread-id part of the query).

notmuch-show can be slow displaying large attachments so hide them by
default. The default maximum size is 10000 bytes/characters but it is
customizable.

Note that notmuch-show-insert-bodypart is also called from the reply
code so we need to be a little careful.

f84cbb1d4d emacs: Rewrite content ID handling
Besides generally cleaning up the code and separating the general
content ID handling from the w3m-specific code, this fixes several
problems.

Foremost is that, previously, the code roughly assumed that referenced
parts would be in the same multipart/related as the reference.
According to RFC 2392, nothing could be further from the truth:
content IDs are supposed to be globally unique and globally
addressable.  This is nonsense, but this patch at least fixes things
so content IDs can be anywhere in the same message.

As a side-effect of the above, this handles multipart/alternate
content-IDs more in line with RFC 2046 section 5.1.2 (not that I've
ever seen this in the wild).  This also properly URL-decodes cid:
URLs, as per RFC 2392 (the previous code did not), and applies crypto
settings from the show buffer (the previous code used the global
crypto settings).

991efcded8 emacs: Remove broken `notmuch-get-bodypart-content' API
`notmuch-get-bodypart-content' could do two very different things,
depending on conditions: for text/* parts other than text/html, it
would return the part content as a multibyte Lisp string *after*
charset conversion, while for other parts (including text/html), it
would return binary part content without charset conversion.

This commit completes the split of `notmuch-get-bodypart-content' into
two different and explicit APIs: `notmuch-get-bodypart-binary' and
`notmuch-get-bodypart-text'.  It updates all callers to use one or the
other depending on what's appropriate.

021906d6ec emacs: Create an API for fetching parts as undecoded binary
The new function, `notmuch-get-bodypart-binary', replaces
`notmuch-get-bodypart-internal'.  Whereas the old function was really
meant for internal use in `notmuch-get-bodypart-content', it was used
in a few other places.  Since the difference between
`notmuch-get-bodypart-content' and `notmuch-get-bodypart-internal' was
unclear, these other uses were always confusing and potentially
inconsistent.  The new call clearly requests the part as undecoded
binary.

This is step 1 of 2 in separating `notmuch-get-bodypart-content' into
two APIs for retrieving either undecoded binary or decoded text.

7585e8c906 emacs: with-current-notmuch-show-message' should not leak coding-system-for-read'
`with-current-notmuch-show-message' applies a `no-conversion' coding
system when reading a raw message from notmuch. That coding system
should _not_ be applied when the body of the macro is evaluated, as it
can cause file operations used during that evaluation to incorrectly
apply the `no-conversion' coding system.

This was discovered when a user's .signature file contained non-ASCII
characters. When a message is forwarded, the `no-conversion' coding
system was applied to the reading of the .signature file, resulting in
raw rather than UTF-8 interpretation of the data.

f47eeac0b0 emacs: set default in notmuch-read-query
This adds the current query as a "default value" to
notmuch-read-qeury. The default value is available via a down-arrow as
opposed to history which is available from the up arrow.

Note if a user presses return in the minibuffer this value is not
returned.

The implementation is simple but notmuch-read-query could be called
via notmuch-search/notmuch-tree etc from any buffer so it makes sense
to put the decision of how to extract the current query in
notmuch-read-query rather than in each of the callers.

2e1eee3a77 emacs: show: add an update seen function to post-command-hook
Add a function for updating seen messages to the
post-command-hook. This function calls a customizable (by eg
defcustom) function with parameters the start and end of the current
window and that function can decide what to mark read based on that
and the current point.

Since this is in the post-command-hook it should get called after most
user actions (exceptions include user resizing the window) so it
should be possible to make sure the seen status gets updated whether
the user uses notmuch commands like next-message or normal emacs
commands like scroll-up.

It removes all of the old mark read/seen points but introduces a
simple example function that just marks the current message read if it
is open. This function has one small subtlety: it makes sure it
doesn't mark the same message read twice (in the same instance of the
same buffer); otherwise the post-command-hook makes it impossible for
a user to manually mark a message unread.

This fixes the current bugs (imo) that closed messages can be marked
read, and that opening a closed message does not mark it read.

Another advantage of using the post-command-hook any programmatic use
with point passing through a message will not mark it read.

ecef282a16 emacs: allow functions in notmuch-show-stash-mlarchive-link-alist
Some archives may use a more complicated scheme for referring to
messages than just concatenated url and message-id. In particular,
patchwork requires a query to translate message-id to a patchwork
patch id. Allow functions in notmuch-show-stash-mlarchive-link-alist
to facilitate this.

For example, one could use something like this for patchwork.

(lambda (message-id)
  (concat
   "http://patchwork.example.com/patch/"
   (nth 0
	(split-string
	 (car (last (process-lines "pwclient" "search" "-n" "1"

a673d618d1 emacs: show: use orig-tags for tag display

941e172724 emacs: show: mark tags changed since buffer loaded
This allows (and requires) the original-tags to be passed along with
the current-tags to be passed to notmuch-tag-format-tags. This allows
the tag formatting to show added and deleted tags.By default a removed
tag is displayed with strike-through in red (if strike-through is not
available, eg on a terminal, inverse video is used instead) and an
added tag is displayed underlined in green.

If the caller does not wish to use the new feature it can pass
current-tags for both arguments and, at this point, we do exactly that
in the three callers of this function.

Note, we cannot tidily allow original-tags to be optional because we would
need to distinguish nil meaning "we are not specifying original-tags"
from nil meaning there were no original-tags (an empty list).

We use this in subsequent patches to make it clear when a message was
unread when you first loaded a show buffer (previously the unread tag
could be removed before a user realised that it had been unread).

The code adds into the existing tag formatting code. The user can
specify exactly how a tag should be displayed normally, when deleted,
or when added.

Since the formatting code matches regexps a user can match all deleted
tags with a ".*" in notmuch-tag-deleted-formats.  For example setting
notmuch-tag-deleted-formats to '((".*" nil)) tells notmuch not to show
deleted tags at all.

All the variables are customizable; however, more complicated cases
like changing the face depending on the type of display will require
custom lisp.

Currently this overrides notmuch-tag-deleted-formats for the tests
setting it to '((".*" nil)) so that they get removed from the display
and, thus, all tests still pass.

7023466ece Make keys of notmuch-tag-formats regexps and use caching
This modifies `notmuch-tag-format-tag' to treat the keys of
`notmuch-tag-formats' as (anchored) regexps, rather than literal
strings.  This is clearly more flexible, as it allows for prefix
matching, defining a fallback format, etc.  This may cause compatibility
problems if people have customized `notmuch-tag-formats' to match tags
that contain regexp specials, but this seems unlikely.

Regular expression matching has quite a performance hit over string
lookup, so this also introduces a simple cache from exact tags to
formatted strings.  The number of unique tags is likely to be quite
small, so this cache should have a high hit rate.  In addition to
eliminating the regexp lookup in the common case, this cache stores
fully formatted tags, eliminating the repeated evaluation of potentially
expensive, user-specified formatting code.  This makes regexp lookup at
least as fast as assoc for unformatted tags (e.g., inbox) and *faster*
than the current code for formatted tags (e.g., unread):

                    inbox (usec)   unread (usec)
    assoc:              0.4            2.8
    regexp:             3.2            7.2
    regexp+caching:     0.4            0.4

(Though even at 7.2 usec, tag formatting is not our top bottleneck.)

This cache must be explicitly cleared to keep it coherent, so this adds
the appropriate clearing calls.

ec13bd12e3 emacs: use the originating buffer's working directory for pipe
Currently notmuch-show-pipe-message runs the command in the working
directory of the *notmuch-pipe* buffer if it exists, and the current
buffer's working directory (which is inherited to the new
*notmuch-pipe* buffer) otherwise. This is all very surprising to the
user, and it's difficult to know or change where the command will be
run.

Always use the current show buffer's working directory for piping. The
user can check that with M-x pwd and change it with M-x cd. This is
consistent with notmuch-show-pipe-part.

9c25d4bbf0 emacs: show: stop stderr appearing in buffer
In emacs 24.3+ the stdout/stderr from externally displaying an
attachment gets inserted into the show buffer. This is caused by
changes in mm-display-external in mm-decode.el.

Ideally, we would put this output in the notmuch errors buffer but the
handler is called asynchronously so we don't know when the output will
appear. Thus if we put it straight into the errors buffer it could get
interleaved with other errors. Also we can't easily tell when we
have got all the error output so can't wait until the process is complete.

One solution would be to create a new buffer for the stderr of each
attachment viewed. Again, since we can't tell when the process has
finished, we can't close these buffers automatically so this will
leave lots of buffers around.

Thus we add a debug variable notmuch-show-attachment-debug: it this is
non-nil we create a new buffer for each viewer; if this variable is
nil we just use a temp buffer which means all error output is
discarded (this is the same behaviour as with emacs pre 24.3).

47792533b3 emacs: Use interactive specifications for tag changes in show
This modifies all tagging operations in show to call
`notmuch-read-tag-changes' in their interactive specification to input
tag changes, rather than depending on lower-level functions to prompt
for tag changes regardless of their calling context.

Besides being more Elispy and providing a more consistent programmatic
API, this enables callers to provide two call site-specific pieces of
information: an appropriate prompt, and the set of visible tags.  The
prompt lets us differentiate * from +/-.  Providing visible tags
enables a more consistent user experience than retrieving the
(potentially different) tags from the database, and avoids a
round-trip to the CLI and database.
