42d32713be emacs: define a few variables as automatically buffer-local
Define these variables as automatically buffer-local, meaning that
they always become buffer-local when set unless explicitly told
otherwise using `setq-default' or when using the Custom interface.

Previously they were declared, which keeps the byte-compiler quiet but
is not actually the same as being defined.  `notmuch-search-mode' then
made them buffer-local in the current buffer and then set the local
values.  This works but is not kosher.

The definitions of the three non-option variables have to be moved up
a bit to enable the change in the next commit, which see.

b614ea7563 emacs: remove variable notmuch-search-disjunctive-regexp
The value is the only possible value, it is only used in one
place, and using a global variable serves no purpose but to
make things more complicated.

37bb41a792 emacs: notmuch-mua-prompt-for-sender: don't force Ido on users
We shouldn't force `ido-completion-read' on users who do not otherwise
use Ido.  Unfortunately simply turning on `ido-mode' does not change
every `completing-read' into a `ido-completing-read', instead it only
changes file and buffer completion.

I do realize that existing Ido users will initially dislike this
change, but I would like to encourage them to see this as an
opportunity to learn about Fido.

Unlike `ido-mode', build-in `fido-mode' confirms to the standard
completion API, so turning it on causes every `completing-read' to
use the Fido completion mechanism and which is similar to the Ido
mechanism:

> An enhanced `icomplete-mode' that emulates `ido-mode'.  This global
> minor mode makes minibuffer completion behave more like `ido-mode'
> than regular `icomplete-mode'."

93c95802a4 emacs: inline notmuch-sexp-eof into only caller
This function had a few issues.
- Neither its name nor the old comment before it is called made it
  clear what it does.
- It took one argument but didn't do anything with it.
- It's doc-string made a few claims, which are untrue and generally
  focused on details instead of that its purpose is.

0067a43ea2 emacs: deal with unused lexical arguments and variables
The previous commit switched to lexical-binding but without dealing
with the new warnings about unused lexical arguments and variables.

This commit deals with most of them, in most cases by either removing
leftover bindings that are actually unnecessary, or by marking certain
arguments as "known to be unused" by prefixing their names with "_".

In the case of the functions named `notmuch-show-insert-...' the
amount of silencing that is required is a bit extreme and we might
want to investigate if there is a better way.

In the case of `notmuch-mua-mail', ignoring CONTINUE means that we do
not fully follow the intended behavior described in `compose-mail's
doc-string.

fc4cda07a9 emacs: use lexical-bindings in all libraries
Doing so causes many new compile warnings.  Some of these warnings
concern genuine changes in behavior that have to be addressed right
away.

Many other warnings are due to unused variables.  Nothing has changed
here, except that the byte-compiler can now detect these pre-existing
and harmless issues.  We delay addressing these issues so that we can
focus on the important ones here.

A third group of warnings concern arguments that are not actually used
inside the function but which cannot be removed because the functions
signature is dictated by some outside convention.  Silencing these
warning is also delayed until subsequent commits.

2ca941163d emacs: make headings outline-minor-mode compatible
`outline-minor-mode' treats comments that begin with three or more
semicolons as headings.  That makes it very convenient to navigate
code and to show/hide parts of a file.

Elips libraries typically have four top-level sections, e.g.:

;;; notmuch.el --- run notmuch within emacs...
;;; Commentary:...
;;; Code:...
;;; notmuch.el ends here

In this package many libraries lack a "Commentary:" section, which is
not optimal but okay for most libraries, except major entry points.

Depending on how one chooses to look at it, the "... ends here" line
is not really a heading that begins a section, because it should never
have a "section" body (after all it marks eof).

If the file is rather short, then I left "Code:" as the only section
that contains code.  Otherwise I split the file into multiple sibling
sections.  The "Code:" section continues to contain `require' and
`declare-function' forms and other such "front matter".

If and only if I have split the code into multiple sections anyway,
then I also added an additional section named just "_" before the
`provide' form and shortly before the "...end here" line.  This
section could also be called "Back matter", but I feel it would be
distracting to be that explicit about it.  (The IMO unnecessary but
unfortunately still obligatory "... ends here" line is already
distracting enough as far as I am concerned.)

Before this commit some libraries already uses section headings, some
of them consistently.  When a library already had some headings, then
this commit often sticks to that style, even at the cost inconsistent
styling across all libraries.

A very limited number of variable and function definitions have to be
moved around because they would otherwise end up in sections they do
not belong into.

Sections, including but not limited to their heading, can and should
be further improved in the future.

adc123e4fd emacs: avoid killing process buffer when process is still alive
In practice this probably does not make a difference or we would
have heard about it many times, but better be safe than sorry.

904ffbc925 emacs: avoid passing around some redundant information
When running "notmuch" we use its full path but when displaying the
command to the user we show just its name for readability reasons.
Avoid passing around both representations because it is very easy
to get the name from the path.

Notmuch itself uses the involved functions just for "notmuch" but
there might be extensions that use them for other executable so we
forgo other potential simplifications.

The buffer of the error process is accessible using `process-buffer'.
We still have to store the error-buffer in the non-error process

d7b83385af emacs: sanitize dedicated widget action/notify functions
These functions are used as action/notify functions.  That dictates
the appropriate function signatures but even though these functions
are not used for anything else they use incompatible signatures,
forcing the callers to use lambda expressions to deal with these
incompatibilities.

Fix that by adjusting the function signatures to the needs of the
only intended callers.

Two of these functions were defined as commands but because the
interactive form did not return the mandatory arguments, we know
that nobody (successfully) used these as commands.

In one case we move the location of a y-or-n-p prompt.

0251cab3ab Revert "emacs: notmuch-search: avoid wiping out buffer-local variables"
This reverts commit f9fbd1ee3b.

Emacs provides a mechanism for avoiding wiping out buffer-local
variables: marking them as "permanent local", which essentially
means "don't wip out the local value when enabling major-mode".

  (put 'the-variable 'permanent-local t)

See (info "(elisp)Creating Buffer-Local").

Whether refreshing the buffer contents should involve re-enable the
mode is a different question, which should not be decided based on
the fact that we want keep the value of some random variable, not
least because some other (e.g. cache) variables are likely expected
to be wiped.

adfded9ed0 emacs: avoid binding unnamed commands in keymaps
One should never bind unnamed commands in keymaps because doing that
makes it needlessly hard for users to change these bindings.

Replace such anonymous bindings with named commands that are generated
using macros and some boilerplate. Using macros is better than using a
simple loop because that makes it possible for `find-function' to find
the definitions. Eat your boilerplate--it forms character.

Admittedly this approach is quite ugly and it might be better to teach
the original commands to support different buffers directly instead of
requiring wrapper commands to do just that.

Never-the-less as a short-term solution this is better than what we
had before.

4f57e01843 emacs: inline notmuch-documentation-first-line
Inline a simplified version of `notmuch-documentation-first-line'
into its only caller.  The new code snippet differs from the
removed function in that it returns nil instead of the empty string
for symbols that have no function documentation.  That value is
ultimately used as an argument to `concat', which treats nil like
the empty string.  So we can do the logical thing without changing
the behavior.
