In order to make it easier to keep the whitespace consistent in the
configure script, use the same style defined in devel/STYLE for
C/C++.
Specifically, a line should begin with zero or more tabs followed
by fewer than eight spaces.
Presumably this will be no more difficult for people editing configure
than for people editing the C and C++ code.
'check-notmuch-commit' is an updated version of a script I have been
using (although not always as consistently as I should) before sending
patches to the list.
Although it requires a bit more tooling, encouraging people to use
check-notmuch-commit might reduce the number of round trips to the
list for style nitpicks.
As discussed at [1] we have received reports that the implicit check
using cffi.FFI().verify() is not reliable in all environments. Since
we already use pkg-config, and the python dev package should include a
.pc file [2], add an extra check using pkg-config. On at least
Debian, we have to know which version of python dev files with are
looking for, so calculate that first.

As reported in id:87h7pxiek3.fsf@tethera.net, the previous version of
the test is flaky. There is some so-far undebugged interaction between
openssl and gpgsm that causes the keys to fail to import. As a
potential workaround, use the key as exported by gpgsm, and eliminate
openssl from this particular pipeline.
New customizable variable, notmuch-tree-thread-symbols, that allows
tweaking of how trees in a forest are represented. For instance, one
can now choose to use an hyphen rather than a white space as a prefix,
or replace the character(s) used to draw arrows.

As with notmuch--process-lines, initial purpose is to provide a safe
binding for default-directory. This is enough to make notmuch-hello
robust against non-existent or corrupt values default-directory, but
probably not other views.
Initially just set the working directory, to avoid (the implicit)
call-process crashing when the default-directory points to a
non-existent location.
Use of a macro here is over-engineering for this change, but the same
change needs to be applied to several other process creation
primitives.
Because of the way emacs reports errors, a test form can crash and not
change the main buffer. To work around this, capture both signalled
errors and any other messages.
As discussed in the thread starting at [1], the fully qualified domain
name is a bit tricky to get reproducibly, might reveal information
people prefer to keep private, and somewhat unlikely to provide
reliable mail routing.
The new approach of $current_username@localhost is better for the
first two considerations, and probably at least as good as a test mail
address.

Add the function notmuch-test-result-flags to test-lib.el to avoid
repeating it in 3 T*.sh files.
If the car of an element in notmuch-tree-result-format or
notmuch-unthreaded-result-format is a function, insert the result of
calling the function into the buffer.
If the car of an element in notmuch-search-result-format is a
function, insert the result of calling the function into the buffer.
This allows a user to generate custom fields in the output of a search
result. For example, with:
(defun -notmuch-result-flags (format-string result)
(let ((tags-to-letters '(("flagged" . "!")
("unread" . "u")
("mine" . "m")
("sent" . "s")
("replied" . "r")))
(tags (plist-get result :tags)))
(format format-string
(mapconcat (lambda (t2l)
(if (member (car t2l) tags)
(cdr t2l)
" "))
tags-to-letters ""))))
(setq notmuch-search-result-format '((-notmuch-result-flags . "%s ")
("date" . "%12s ")
("count" . "%9s ")
("authors" . "%-30s ")
("subject" . "%s ")
("tags" . "(%s)")))
The first few characters on each line of the search result are used to
show information about some significant tags associated with the
thread.
With [1: 16b2db09] we lost the (undocumented) option to use no Fcc
header only for From addresses matching a regexp. This brings back
that feature and documents it.

emacs: various cosmetic improvements
We have to rewrite _optimize_tag_query here because it is generating
a query string in the infix Xapian syntax. Luckily this is easy to do
with the sexp query syntax.
The change in each case is to call notmuch_query_create_with_syntax,
relying on the already inherited shared options. As a bonus we get
improved error handling from the new query creation API.
The remaining subcommand is 'tag', which is a bit trickier.
Macros implement lazy evaluation and lexical scope. The former is
needed to make certain natural constructs work sensibly (e.g. (tag
,param)) but the latter is mainly future-proofing in case the DSL is
is extended to allow local bindings.
For technical background, see chapters 6 and 17 of [1] (or some other
intermediate programming languages textbook).

It turns out there is not really much code in query-fp.cc useful for
supporting the new syntax. The code we could potentially factor out
amounts to calling notmuch_database_get_config; both the key
construction and the parsing of the results are specific to the query
syntax involved.
This commit does not enable using saved s-expression queries, only
saving and retrieving them from the config file or the database. Use
in queries will be enabled in a following commit.
This provides functionality analogous to query: in the Xapian
QueryParser based parser. Perhaps counterintuitively, the saved
queries currently have to be in the original query syntax (i.e. not
s-expressions).
One subtle aspect is the replacement of _find_prefix with
_notmuch_database_prefix, which understands user headers. Otherwise
the code mainly consists of creating a fake prefix record (since the
user prefixes are not in the prefix table) and error handling.
This is necessary so that programs can take infix syntax queries from
a user and use the sexp query syntax to construct e.g. a refinement of
that query.
It will be convenient not to have to construct a notmuch query object
when parsing subqueries, so the commit rewrites the query
expansion (currently only used for thread:{} queries) using only
Xapian. As a bonus it seems about 15% faster in initial experiments.
