* etc/NEWS: Announce change to matching color fonts when using XFT.
* src/ftfont.c (ftfont_list) [HAVE_XFT && FC_COLOR]: Query for the
color attribute of the matched font, and skip it if it is not
FcFalse (Bug#37786).
* lisp/emacs-lisp/cl-extra.el (cl-random):
Perform the modulo 2**23 operation before updating the state instead
of after. The result is always the same, but it prevents the state
from growing into arbitrary large bignums.
Patch from Christopher Wellons.
* lisp/progmodes/project.el (project-files):
Remove (require 'xref).
(project--files-in-directory): Add it here instead.
(project-find-regexp, project-or-external-find-regexp): And here.
For 'xref--show-xrefs'.
* lisp/progmodes/xref.el (xref-matches-in-files): Extract from
project--find-regexp-in-files.
* lisp/dired-aux.el (dired-do-find-regexp): Also use it here.
* lisp/progmodes/xref.el (xref-references-in-directory): Rename
from xref-collect-references. Update the sole caller.
(xref-matches-in-directory): Rename from xref-collect-matches.
Update all callers (all of them are in the /tests/ dir).
* test/lisp/progmodes/xref-tests.el (xref-tests-data-dir):
Don't use the EMACS_TEST_DIRECTORY env var. It doesn't work when
running interactively.
* lisp/progmodes/xref.el (xref--last-file-buffer):
Rename from xref--last-visiting-buffer. Update users.
(xref--find-file-buffer): Rename from xref--find-buffer-visiting
to match the standard function that gets called inside. Ditto.
* etc/NEWS: Rearrange and mark entries whether documented or not.
* doc/lispref/streams.texi (Output Variables): Document the new
default of 'print-quoted'.
* doc/lispref/keymaps.texi (Functions for Key Lookup): Document
that KEYMAP arg to 'lookup-key' can also be a list.
* doc/lispref/customize.texi (Variable Definitions): Document the
:local keyword of 'defcustom'.
* doc/lispref/numbers.texi (Float Basics): Document changes in
'logb'.
* doc/lispref/hooks.texi (Standard Hooks): Document
'comint-password-function'.
* doc/emacs/display.texi (Text Scale): Document text-size
adjustment using the mouse wheel.
* doc/emacs/frames.texi (Mouse Commands): Document image scaling
with the mouse wheel.
* doc/emacs/windows.texi (Window Convenience): Document
'global-tab-line-mode'.
* doc/emacs/search.texi (Repeat Isearch, Symbol Search)
(Isearch Yank): Document the new support for numeric arguments in
Isearch commands.
(Special Isearch): Document 'M-s M->' and 'M-s M-<'.
(Search Customizations): Document 'isearch-lazy-count'. Improve
indexing.
(Not Exiting Isearch): Document the new value of
'isearch-allow-scroll'.
* doc/emacs/maintaining.texi (Xref Commands): Document the new 'g'
key binding.
* doc/emacs/package.texi (Package Installation): Document changes
in 'package-check-signature'.
* doc/emacs/maintaining.texi (VC Change Log): Document
'vc-log-search'.
* doc/emacs/dired.texi (Operating on Files): Document
'dired-vc-rename'.
* doc/lispref/functions.texi (Obsolete Functions): Make
documentation of functions that obsolete symbols match the
advertised calling conventions.
* lisp/emacs-lisp/byte-run.el (define-obsolete-function-alias)
(define-obsolete-variable-alias, define-obsolete-face-alias):
State in the doc strings that WHEN is a mandatory argument, to be
consistent with the advertised calling convention. (Bug#38675)
* lisp/gnus/gnus-start.el (gnus-group-change-level): Fix previous
patch that made info nil when adding new groups (thereby making
gnus-newsrc-alist invalid).
* lisp/progmodes/project.el (project-try-vc): Do not treat a Git
submodule as a project root, go up to the parent repo.
(project--git-submodules): New function.
(project--vc-list-files): Use it. Recurse into submodules.
* doc/emacs/buffers.texi (Buffers): Say that buffers are killed
when no longer needed. Suggested by Jean-Christophe Helary
<jean.christophe.helary@traduction-libre.org>.
* lisp/calc/calc-alg.el (math-simplify-only, calc-simplify-mode)
(math-expand-formulas, calc-poly-div-remainder)
(math-living-dangerously, math-simplifying, calc-angle-mode)
(calc-prefer-frac, math-poly-base-variable):
Declare dynamic variables.
* test/lisp/calc/calc-tests.el (calc-poly-div):
Add test for at least one bug caused by missing declarations.
* lisp/dired-aux.el (dired-do-find-regexp): Speed up (bug#36857).
Previously, 'find' was called for every marked file (for plain
files and directories both). Now 'find' is only called for
directories.
'module-load' most likely doesn't do what users expect. Users should
use 'load' and its wrappers, which do the right thing.
* doc/lispref/loading.texi (Dynamic Modules): Document
disadvantages of 'module-load' and recommend normal 'load' and
its wrappers instead.
* doc/lispref/internals.texi (Module Functions): Recommend
'load' over 'module-load'.
* src/xfns.c (x_get_net_workarea) [!HAVE_GTK3]:
Define in this case too, since x_get_monitor_attributes_fallback
contains a call to it regardless whether HAVE_GTK3 is defined.
* lisp/vc/vc.el (vc--add-line): Create file if it does not exist.
Use existing buffer to avoid discrepancies with filesytem. Make sure
that the file ends with a newline.
(vc--remove-line): Do not create file if it does not exist. Use
existing buffer to avoid discrepancies with filesytem. (bug#37185)
* lisp/gnus/gnus-art.el (gnus-article-x-face-command): It's seldom
useful to display the face in an external command, so don't ever
default to that. This also fixes the problem of Emacs running as
a server in mixed graphical/non-graphical environments.
* src/coding.c (Fencode_coding_region): Clarify what this does.
(Fdecode_coding_region): Ditto.
* src/fns.c (Fbase64_decode_region): Clarify that this function
returns bytes, not text (bug#38587).
(Fbase64_encode_region): Clarify that this function takes bytes,
not text.
* src/image.c (imagemagick_initialize): New function,
with body taken from imagemagick_load_image.
(imagemagick_load_image, Fimagemagick_types): Use it.
