* lisp/textmodes/bibtex.el (bibtex-BibTeX-entry-alist):
Change :group from BibTeX to bibtex.  (bug#32436)

* doc/misc/calc.texi (Internals): Don't advertise
'calc-extensions' which no longer exists.  Reported by Francis
Wright <francis.j.wright@gmail.com>.

Problem reported by Eli Zaretskii in:
https://lists.gnu.org/r/emacs-devel/2018-08/msg00380.html
* src/data.c (arithcompare): Work around incompatibility
between gcc -fexcess-precision=fast and the C standard on x86,
by capturing the results of floating-point comparisons before
the excess precision spontaneously decays.  Although this fix
might not work in general, it does work here and is probably
good enough for the platforms we care about.

(cherry picked from commit a84cef90)

* test/src/data-tests.el (data-tests--float-greater-than-fixnums):
New constant.
(data-tests-=, data-tests-<, data-tests->, data-tests-<=)

Toggle the locked status in marked buffers or the buffer
at point (Bug#32421).
* lisp/ibuffer.el (ibuffer-do-toggle-lock): New command.
(ibuffer-mode-map): Bind it to 'L'.
(ibuffer-mode-operate-map): Add entries for

(shadow-test06-literal-groups, shadow-test07-regexp-groups)
(shadow-test08-shadow-todo, shadow-test09-shadow-copy-files):
Use `set-visited-file-name' instead of setting the value in
`buffer-file-name' directly.
(shadow-test08-shadow-todo, shadow-test09-shadow-copy-files):
Test for writable temporary directory.  Suppress errors in
cleanup.  (Bug#32226)

Packages which are not directly user-installed shouldn't be autoremoved,
since they can be setup through a different path (via
`package-directory-list') where we have no authority over.
* lisp/emacs-lisp/package.el (package--user-installed-p): New
function.
(package--removable-packages): Use it.

* lisp/international/mule.el (sgml-html-meta-auto-coding-function):
Support UTF-8 with BOM and utf-8-hfs as variants of UTF-8, and
obey the buffer's encoding if it is one of these variants, instead
of re-encoding in UTF-8 proper.  (Bug#20623)

* configure.ac: Add -Wabi to the list of disabled warning
options.  For the details, see
http://lists.gnu.org/archive/html/emacs-devel/2018-08/msg00123.html.

where the next spec with another property begins.  (Bug#32404)

* test/src/editfns-tests.el (format-properties): Add tests for
bug#32404.

* lisp/startup.el (command-line-1) <initial-buffer-choice>: Make the
messages conform to Emacs conventions, and show the invalid return
value in the message.

* src/fileio.c (get_file_errno_data): Refactor out into its own
function so that we can reuse the error handling from an async

'local client fails (with a file error, for instance), mark the

* src/xdisp.c (redisplay_window): Make sure desired_matrix is
cleared before calling try_window.  This is important when

assumes each glyph row is completely cleared when it is called to
produce a line number.  (Bug#32358)

modify_text_properties modifies the interval tree as side effect,

* lisp/wdired.el (wdired-search-and-rename): Remove dired-filename
text property in order to find new filename when it only partially
replaces old filename (bug#32173).  If user quits before renaming
succeeds, restore the dired-filename text property.

* doc/lispref/eval.texi (Special Forms):
* doc/lispref/frames.texi (Mouse Tracking): 'track-mouse' is
nowadays a macro.  (Bug#32284)

test.
