* doc/lispref/os.texi (Time Calculations): Mention the meaning of
'nil' or a scalar number as the time-value argument. Add a
cross-reference to 'float-time' for computing a time difference as
a scalar number of seconds.
* src/editfns.c (Fformat_time_string, Ftime_less_p)
(Ftime_subtract, Ftime_add, Fdecode_time, Fcurrent_time_string)
(Fcurrent_time_zone): Mention in the doc strings the meaning of
nil argument and the fact that a time value can be a scalar number
of seconds since the epoch.
(Ftime_subtract): Mention 'float-time'.
* lisp/international/fontset.el (setup-default-fontset): Make sure
Symbola and FreeMono are set up in the default fontset as belonging
to the "iso10646-1" registry. In the UTF-8 locale, this avoids a
long and futile search for a suitable font, whose side effect is a
lot of consing, which then hits the font-cache compacting issue,
and causes very sluggish redisplay of characters displayed by
these fonts. All this happens because the default for the
registry is "iso8859-1". (Bug#24953)

* doc/lispref/control.texi (Pattern matching case statement):
* doc/lispref/frames.texi (Size and Position):

Do not upper-case the argument of @var.
doc/emacs/modes.texi (Major Modes): Amend the statement about programming
modes running prog-mode-hook to say that it applies to many (not all) such
modes, and specifying exactly which modes.
"Don't call debug on failed cl-assert..." removed the call to `debug' in
cl--assertion-failed because `debug' calls `kill-emacs' in batch mode,
thus messing up ert test runs. However, calling the debugger is useful
because it allows catching failed assertions even inside
`condition-case' calls. The problem with ert can be avoided by calling
`debugger' instead of `debug' directly, since ert installs its own
debugger while running tests.
* lisp/emacs-lisp/cl-preloaded.el (cl--assertion-failed): Call
`debugger' if `debug-on-error' is non-nil.
Fix bug#24905
* lisp/progmodes/python.el (python-info-docstring-p): Improve
infloop avoidance: replace (bobp) with generic test for
forward progress.
* test/lisp/progmodes/python-tests.el (python-bob-infloop-avoid): Add
test for bug#24905
2015-02-07 "Fix hideshow integration[...]" changed the regexp added to
`hs-special-modes-alist' so that it worked when not searching from the
beginning of the line. However, this allows matching tokens ending in
"def" or "class", not just those keywords. This results in an infinite
loop in hs-hide-all (Bug #24815).
* lisp/progmodes/python.el (python-mode): Add symbol boundaries around
the def|class matching part of the regexp added to
hs-special-modes-alist.
Apple changed the spelling of its operating system again, to "macOS",
effective with macOS 10.12 Sierra (2016-09-20). Change Emacs
documentation and comments to match this. Stick with older OS
spellings ("OS X", "Mac OS X") when talking about older releases where
the older names are more correct.
Emacs C code assumes C99 features, but has long used traditional
comments /* like this */ instead of C99-style comments // like this.
Stick with traditional comments for now, partly for style, partly as
it may be safer with compilers that are not fully in C99 mode.
Doing this causes problems when running ert tests, for
instance (Bug#24778). The call to `debug` when `debug-on-error' is
non-nil was introduced in 2015-02-14 "* lisp/emacs-lisp/cl*.el: Use
define-inline and move some code...".
* lisp/emacs-lisp/cl-preloaded.el (cl--assertion-failed): Don't call
`debug' directly.
* nt/README.W32: Describe 64 and 32-bit downloads, optional
dependencies bundle. Remove old material on sourcing dependencies.
Remove references to Windows 95. Update GUI references to recent
Windows. Remove references to Usenet.
* lisp/vc/vc.el (vc-responsible-backend): Clarify that symlinks
are not resolved when the VC backend is reported.
* doc/lispref/files.texi (Truenames): Document
'vc-responsible-backend'. (Bug#23436)
* doc/emacs/maintaining.texi (Version Control Systems): Fix a
typo.
* lisp/simple.el (transpose-sexps): Clarify the conditions for
transposing sexps that are lists or strings. Mention the effect
of the prefix argument. (Bug#24860)
* doc/lispref/modes.texi (Customizing Keywords): Clarify the
'keywords' argument of 'font-lock-remove-keywords'. Suggested by
Hong Xu <hong@topbug.net>. (Bug#24830)
* doc/misc/eudc.texi (Inline Query Expansion): Fix the default value of
'eudc-inline-expansion-format'. (Bug#24840)
Backport:
(cherry picked from commit 1fef1387c3)
With Python 3.5, (python-shell-completion-native-get-completions ... "")
would return an empty list, causing python.el to think that native
completion was unavailable (the difference between Python 2 and Python 3
is due to https://bugs.python.org/issue25660).
* lisp/progmodes/python.el (python-shell-completion-native-try): Use "_"
to check whether native completion is available instead of "".
