* src/fns.c (Fline_number_at_pos): Pass character position to
args_out_of_range. Suggested by Andreas Schwab
<schwab@linux-m68k.org>. Call args_out_of_range_3 to show both
ends of the accessible portion.
* src/gmalloc.c (hybrid_free_1): New function, with the body of
the previous 'hybrid_free'.
(hybrid_free): Call 'hybrid_free_1' while preserving the value of
'errno'. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
* src/conf_post.h [HYBRID_MALLOC || DARWIN_OS && HAVE_UNEXEC]:
Include <stdlib.h> here, before redirecting 'malloc' and friends
to their hybrid_* and unexec_* equivalents. #undef malloc and
friends before redefining. Provide prototypes for the
replacements. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
* src/gmalloc.c [HYBRID_MALLOC]: Remove declarations of 'malloc'
and friends, as they are now redundant: we include <stdlib.h> in
conf_post.h before redefining 'malloc' etc., and that provides
prototypes from system headers.
* configure.ac (HYBRID_MALLOC): Remove kludge to avoid replacement
of 'free' by Gnulib. (Bug#36649)
* doc/emacs/maintaining.texi (Maintaining): Add a section about
bug-reference-mode.
* doc/emacs/emacs.texi (Top): Link to the new section about
bug-reference-mode.
* lisp/window.el (window-default-font-height): Avoid signaling an
error when a client TTY frame happens to have an X-style 'display'
parameter. (Bug#48408)
The unexec build on GNU/Linux must use HYBRID_MALLOC (gmalloc.c) and
sheap.c. This was inadvertently disabled because a configure-time
test for 'sbrk' was moved as side effect of an unrelated change.
* configure.ac: Test for 'sbrk' before using the result in the
decision about SYSTEM_MALLOC and HYBRID_MALLOC.
(HYBRID_MALLOC): Prevent Gnulib from redirecting 'free' to its
replacement 'rpl_free'.
* lib/Makefile.in (not_emacs_OBJECTS): Add mallooc/%.o and free.o.
* lisp/cus-theme.el (custom-theme-summary): Don't limit the file to
having the deftheme form as the very first form, rather look for the
deftheme form explicitly.
Also remove redundant `:group` arguments.
(eshell-parse-modifiers): Make sure we pass a function value.
(eshell-parse-arg-modifier, eshell-parse-modifiers)
(eshell-add-pred-func, eshell-pred-user-or-group)
(eshell-pred-file-time, eshell-pred-file-type, eshell-pred-file-mode)
(eshell-pred-file-links, eshell-pred-file-size)
(eshell-pred-substitute, eshell-include-members, eshell-join-members)
(eshell-split-members): Use proper closures.
(repeat-exit-timer): New variable.
(repeat-post-hook): Run idle timer with an "exit function"
returned from set-transient-map.
Suggested by Gustavo Barros <gusbrs.2016@gmail.com>.
(repeat-echo-message): Remove own previous message when input arg is nil.
* lisp/window.el (display-buffer-override-next-command): Return exitfun.
The fix to Bug#48489 (commit 9676d41b83)
has masked the symptom of Bug#42701 for 'if-let'. Create a helper
macro that still exemplifies the bug.
* test/lisp/emacs-lisp/edebug-tests.el
(edebug-tests--duplicate-symbol-backtrack): New helper macro.
(edebug-tests-duplicate-symbol-backtrack): Use it instead of 'if-let'.
* lisp/emacs-lisp/eldoc.el (eldoc--echo-area-prefer-doc-buffer-p):
Look for a window displaying the ElDoc documentation buffer in all
visible frames, as promised by the user option
eldoc-echo-area-prefer-doc-buffer (bug#48278).
* lisp/ibuffer.el (ibuffer-visit-buffer-other-window-noselect):
Use display-buffer instead of pop-to-buffer and selecting the old
window. `pop-to-buffer' focuses the new frame, but
`select-window' usually fails to focus the original frame. This
simple patch fixes that (bug#48218).
(kmacro-lambda-form): Remove unused args `counter` and `format`.
Arrange to be able to extract `mac` from the function.
(kmacro-extract-lambda): Use this new extraction instead of digging
into the guts of a function's code.
pcase 'rx' patterns with a single named submatch, like
(rx (let x "a"))
would always succeed because of an over-optimistic transformation.
Patterns with 0 or more than 1 named submatches were not affected.
Reported by Philipp Stephani.
* lisp/emacs-lisp/rx.el (rx--pcase-macroexpander):
Special case for a single named submatch.
* test/lisp/emacs-lisp/rx-tests.el (rx-pcase): Add tests.
