* src/w32.h (register_aux_fd): New function declaration.
* src/w32.c (register_aux_fd): New function.
* src/process.h (struct Lisp_Process): New member stderrproc.
* src/process.c (PIPECONN_P): New macro.
(PIPECONN1_P): New macro.
(Fdelete_process, Fprocess_status, Fset_process_buffer)
(Fset_process_filter, Fset_process_sentinel, Fstop_process)
(Fcontinue_process): Handle pipe process specially.
(create_process): Respect p->stderrproc.
(Fmake_pipe_process): New function.
(Fmake_process): Add new keyword argument :stderr.
(wait_reading_process_output): Specially handle a pipe process when
it gets an EOF.
(syms_of_process): Register Qpipe and Smake_pipe_process.
* doc/lispref/processes.texi (Asynchronous Processes): Document
`make-pipe-process' and `:stderr' keyword of `make-process'.
* lisp/subr.el (start-process): Suggest to use `make-process' handle
standard error separately.
* test/automated/process-tests.el (process-test-stderr-buffer)
(process-test-stderr-filter): New tests.
* etc/NEWS: Mention new process type `pipe' and its usage with the
`:stderr' keyword of `make-process'.
* src/window.c (Frecenter): Use the same code for GUI and TTY
frames alike; use vmotion only for "initial" frames. This is
because vmotion doesn't support visual-line-mode. Rewrite the
'iarg >= 0' case to use move_it_* functions instead of using
vmotion, for the same reason. Fix the clipping of the argument
value to support scroll-margin in all cases and avoid unwarranted
recentering. Reported by Milan Stanojević <milanst@gmail.com> in
http://lists.gnu.org/archive/html/help-gnu-emacs/2015-04/msg00092.html,

* lisp/cedet/semantic/util-modes.el
(semantic-stickyfunc-header-line-format): Emacs<22 is not supported
any more.
* lisp/cedet/semantic/fw.el (semantic-buffer-local-value): Emacs<21 is
not supported any more.
(semantic-safe): Use `declare'.
* lisp/cedet/semantic/decorate.el (semantic-set-tag-intangible)
(semantic-tag-intangible-p): Remove unused functions.
* lisp/cedet/semantic/complete.el (semantic-displayor-window-edges):
Remove unused function.
(gnus-article-hide-text, gnus-article-unhide-text)
(gnus-article-unhide-text-type): Remove special handling of
`intangible' since that property is not used any more.
(gnus-article-treat-body-boundary): Use gnus-hidden-properties.
* build-aux/gitlog-to-emacslog: Use ChangeLog.1, not Makefile.in,
for copyright notice prototype, so that we get a proper "coding:"
cookie. Use 'mv -i' to avoid unconditionally overwriting an
existing ChangeLog. Problems reported by Eli Zaretskii in:
http://lists.gnu.org/archive/html/emacs-devel/2015-04/msg00504.html
Fixes: debbugs:20202
* lisp/net/tramp-sh.el (tramp-remote-process-environment):
* lisp/comint.el (comint-exec-1):
* lisp/term.el (term-exec-1): Don't set EMACS envvar.
* lisp/progmodes/compile.el (compilation-start): Same and bring
INSIDE_EMACS's format in line with other users.
Fixes: debbugs:19755
Thanks to Carlos Pita <carlosjosepita@gmail.com> for reporting
this and providing useful ideas.
* lisp/progmodes/python.el
(python-shell-completion-native-output-timeout): Increase value.
(python-shell-completion-native-try-output-timeout): New var.
(python-shell-completion-native-try): Use it.
(python-shell-completion-native-setup): New readline setup avoids
polluting current context, ensures output when no-completions are
available and includes output end marker.
(python-shell-completion-native-get-completions): Trigger with one
tab only. Call accept-process-output until output end is found or
python-shell-completion-native-output-timeout is exceeded.
Fixes: debbugs:8531
* lisp/eshell/esh-arg.el (eshell-parse-argument-hook): Update comment.
(eshell-parse-backslash): Return escaped character after backslash
if it is special. Otherwise, if the backslash is not in a quoted
string, ignore the backslash and return the character after; if
the backslash is in a quoted string, return the backslash and the
character after.
* test/automated/eshell.el (eshell-test/escape-nonspecial)
(eshell-test/escape-nonspecial-unicode)
(eshell-test/escape-nonspecial-quoted)
(eshell-test/escape-special-quoted): Add tests for new
`eshell-parse-backslash' behavior.
(package--ensure-init-file): Check file contents before visiting.
(package-initialize): Call it.
(package-install-from-buffer, package-install): Don't call it.
* doc/misc/eshell.texi (Input/Output): Add notice that some tools
such as git call less with its -F option which omits pagination if
the contents is less than one page long. This interferes with
eshell's visual (sub-)commands.
* etc/PROBLEMS: Mention visible-cursor; a few more mentions of
~/.Xresources and xrdb(1); refer to 'GNU Coreutils' and
'X Window System' or 'X' (were: 'GNU Fileutils' and 'X Windows',
respectively); other minor updates and tweaks. (Bug#20011)
