I'm on the fence about whether it's actually better like this. I now
find it unpredictable just how far C-M-a will travel in search of a
definition, and Imenu already presents an alternative means of jumping
only to definitions.
But I don't feel too strongly and can see the utility either way, so I
defer to others who write more Autoconf than I do.

Please never rely blindly on people who submit "git format-patch" patches to have the bug number in the log message. They don't always have that, especially if the patch is the first message that creates the debbugs bug, because the number is unknown when the patch is submitted. Please always eyeball the change before pushing, and if needed, use "git commit --amend" to edit the commit log message to add the bug number and fix any other blunders you find there. TIA

Conversely, there may be conditional definitions of functions, e.g.,
Gnulib does this:
AC_DEFUN([gl_ASSERT_NO_GNULIB_TESTS],
[
dnl Override gl_MODULE_INDICATOR_FOR_TESTS.
AC_DEFUN([gl_MODULE_INDICATOR_FOR_TESTS], [])
])
Admittedly this sort of thing is rare.
Could we change the search for defuns to be more selective? It's not
reasonable to think that every AC_.... call is a defun.

The attached patch extends autoconf-mode to:
- also fontify AU_, AX_, and gl_ macro calls as keywords;
- also recognise AH_, AS_, AU_, AX_, LT_, and gl_ macro calls as targets
for beginning-of-defun, but not an opening square bracket in column 0;
- fontify the first argument of AC_DEFINE, AC_DEFINE_UNQUOTED, AC_SUBST,
and AH_TEMPLATE with font-lock-variable-name-face instead of
font-lock-function-name-face;
- also fontify the first argument of AH_VERBATIM, AM_CONDITIONAL, and
AM_MISSING_PROG as a variable;
- fontify the first argument of AC_DEFUN, AC_DEFUN_ONCE, AU_ALIAS,
AU_DEFUN, and function-like AC_DEFINE as a function;
- support backslashes, variable substitutions, and command substitutions
with backticks in the first argument of AC_DEFINE_UNQUOTED; and
- fontify changequote only when it stands freely, not when it is part of
m4_changequote (where either the whole macro name should be fontified,
or no part of it).
WDYT?
Also, a question: should defun-prompt-regexp really allow for leading
indentation? In Autoconf scripts of the form:
if ...
...
AC_MSG_...
...
AC_MSG_...
...
fi
it means that beginning-of-defun stops at every indented AC_ or AM_
macro call (and with the attached patch, at any macro call with a known
namespace).
Is this a feature (which allows jumping to the Autoconf parts in a sea
of shell code), or does it break from expected beginning-of-defun
semantics?
Thanks,

Basil

Subject: [PATCH] Improve autoconf-mode macro detection
* doc/lispref/modes.texi (Search-based Fontification): Fix
indentation of (MATCHER . FACESPEC) example.
* doc/misc/cc-mode.texi (Performance Issues): Index
defun-prompt-regexp under variables, not functions.
* lisp/progmodes/autoconf.el (autoconf--symbol, autoconf--macro):
New rx definitions.
(autoconf-definition-regexp): Use an optional second capture group
to indicate a function rather than variable definition. Detect
AC_DEFINE defining a function-like CPP macro. Skip more shell
syntax such as variable ${} expansion and command `` substitution in
AC_DEFINE_UNQUOTED variable. Match AH_VERBATIM, AM_CONDITIONAL, and
AM_MISSING_PROG as defining variables, and AC_DEFUN, AC_DEFUN_ONCE,
AU_ALIAS, and AU_DEFUN as defining functions. Document first
capture group in docstring.
(autoconf-font-lock-keywords): Use autoconf--macro to match more
Autoconf macros, such as those defined in the Autoconf Archive and
Gnulib. Reserve font-lock-function-name-face for function
definitions as determined by autoconf-definition-regexp, and use
font-lock-variable-name-face for the rest instead. Use Font Lock
face symbols directly in place of their corresponding variable.
Fontify M4 changequote primitive only as a standalone symbol.
(autoconf-imenu-generic-expression): Add commentary mentioning new
submenu possibility.
(autoconf-current-defun-function): Update docstring accuracy.
Replace line-end-position with pos-eol since there are no fields.
(autoconf-mode): Define defun-prompt-regexp in terms of
autoconf--macro to support more toplevel macros, such as those
defined in Autoheader, M4sh, etc. Set
open-paren-in-column-0-is-defun-start to nil to avoid false
positives when an Autoconf quote character is in column zero.
* test/lisp/progmodes/autoconf-resources/configure.ac: New file.
* test/lisp/progmodes/autoconf-tests.el
(autoconf-tests-current-defun-function-define)
(autoconf-tests-current-defun-function-subst): Replace character
motion with search.
(autoconf-tests-autoconf-mode-comment-syntax): Ditto. Test both dnl
and # comments. Use syntax-ppss-context.
(autoconf-tests-font-lock): New test.
