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.
When dealing with recursive queries (i.e. thread:{foo}) it turns out
to be useful just to deal with the underlying Xapian objects, and not
wrap them in notmuch objects.
The previous code had the somewhat bizarre effect that the (notmuch
specific) query string was "*" (interpreted as MatchAll) and the
allegedly parsed xapian_query was "MatchNothing".
This commit also reduces code duplication.
At least to the degree that the Xapian QueryParser based parser
also supports them. Support short alias 'rx' as it seems to make more
complex queries nicer to read.
