* lisp/emacs-lisp/easy-mmode.el (easy-mmode--arg-docstring):
Clarify that the minor mode hook is called both when enabling and
disabling the mode (bug#34073).
* lisp/vc/diff-mode.el (diff-error): New face (bug#2739).
(diff-font-lock-keywords): Use it to highlight lines like "diff: "
which are error messages from diff (for instance, when a file
doesn't exist).
* lisp/gnus/nndoc.el (nndoc-possibly-change-buffer): If we're
reading an mbox file, it may contain messages that use
content-transfer-encoding 8bit, which means that we have to treat
the file as a sequence of byte (bug#42951). This avoids
double-decoding -- once by Emacs when inserting the mbox into the
buffer, and once by Gnus when displaying the articles.
* textmodes/ispell.el (ispell-add-per-file-word-list): Add new
LocalWords line just after existing such lines. Good to keep words
together or if deliberately placed somewhere special (bug#20486).
* lisp/gnus/gnus-icalendar.el
(gnus-icalendar-with-decoded-handle): Check whether there is a
charset before using it (bug#40290).
Copyright-paperwork-exempt: yes
* lisp/pcmpl-gnu.el (pcmpl-gnu-make-targets): Require that target
names not be preceded by a TAG character (bug#42411).
Copyright-paperwork-exempt: yes
When 'line-move-visual' is nil, use 'end-of-line' to move point to the end
of the first logical line (bug#42862)
Thanks to Michael Welsh Duggan <mwd@md5i.com>.
* lisp/vc/ediff-diff.el (ediff-prepare-error-list): Decode the
data from diff before displaying (bug#5050). This fixes a problem
with displaying raw bytes in the error messages in non-ASCII locales.
* lisp/image-mode.el (image-mode): Give a less confusing message
if we don't have any image data (bug#16062). Also leave the
buffer in fundamental mode.
Instead of blindly assuming that all Emacs strings are valid UTF-8,
which they are not, use a more careful conversion going via UTF-16
which is what NSString uses internally. Unpaired surrogates will
still go through to the NSString objects, but the NS libs handle them
gracefully.
* src/nsterm.h (EmacsString): New category.
* src/nsfns.m (all_nonzero_ascii): New helper function.
([NSString stringWithLispString:]): New method.
(ns_set_name_internal): Use new conversion method.
* lisp/vc/diff-mode.el (diff-goto-source): Don't output a status
about the hunk just when jumping to it (bug#38370). This would
output "Hunk already applied" when browsing diffs.
* lisp/time.el (world-clock-mode): Set 'revert-buffer-function'
buffer-locally rather than globally.
(display-time-world): Unobsolete alias for 'world-clock'. Some users
might be used to the old name.
Add a customizable variable for driver options (such as linker flags)
to pass to libgccjit (Bug #42761).
* lisp/emacs-lisp/comp.el (comp-native-driver-options): New
customization variable.
* src/comp.c: Use comp-native-driver-options to set libgccjit's driver
options, if supported on the library's ABI version.
'dlopen' can return the same handle if two shared with the same
filename are loaded in two different times (even if the first was
deleted!). To prevent this scenario the last modification time of the
source file is included in the hashing algorithm.
* src/comp.c (Fcomp_el_to_eln_filename): Update hashing algo to
include the source last modification date.
* src/lread.c (maybe_swap_for_eln): Do not check for eln newer
then elc as this is now unnecessary.
* lisp/simple.el (read-extended-command): Allow doing interactive
searches over the completions (bug#12490). This restores the
behaviour from Emacs 23 that was lost in Emacs 24.
This bug affected compilation of
(cond ((member '(some list) variable) ...) ...)
While equal is symmetric, member is not; in the latter case the
arguments must be a variable and a constant list, in that order.
Reported by Ikumi Keita.
* lisp/emacs-lisp/bytecomp.el (byte-compile--cond-switch-prefix):
Don't treat equality and member predicates in the same way; only
the former are symmetric in their arguments.
* test/lisp/emacs-lisp/bytecomp-tests.el
(byte-opt-testsuite-arith-data): Add test cases.
