* net/tramp-sh.el (tramp-sh-handle-start-file-process): Let-bind
`tramp-current-connection' in order to avoid an error when several
commands are invoked in a short time in eshell and friends.

 src/w32proc.c (new_child): Avoid leaking handles if the subprocess
 resources were not orderly released.

Revert changes to w32proc.c done since 2012-11-30T09:23:15Z!eliz@gnu.org.

Do NOT merge to trunk!

 src/w32proc.c (new_child): Remove the loop that attempted to salvage
 slots of dead processes.
 (new_child, delete_child, find_child_pid): Don't insist on
 procinfo.hProcess be NULL for a process slot to be considered
 inactive, or be non-NULL to be considered active.
 (reader_thread): Don't set the FILE_AT_EOF flag of a file
 descriptor if the corresponding child was deleted and its
 char_avail handle is NULL.
 (reap_subprocess): Don't reset the FILE_AT_EOF flag.
 (sys_select): Don't pass a NULL process handle to
 WaitForMultipleObjects.

Fixes: debbugs:13735 debbugs:13546

 src/xdisp.c (x_draw_vertical_border): For a window that is neither
 the leftmost nor the rightmost, redraw both the left and the right
 vertical borders.

Check that response to the starttls-command is non-nil.

Fixes: debbugs:13706

 src/w32proc.c (new_child): Free up to 2 slots of dead processes at a
 time.  Improve diagnostics in DebPrint.
 (reader_thread): If cp->char_avail is NULL, set the FILE_AT_EOF
 flag, so that sys_select could have a chance of noticing that this
 process is dead, and call a SIGCHLD handler for it.  Improve
 diagnostics in DebPrint.
 (reap_subprocess): Reset the FILE_AT_EOF flag set by
 reader_thread.
 (sys_select): Watch a process whose procinfo.hProcess is non-NULL
 even if its char_avail is NULL.  Allows to reap subprocesses that
 were forcibly deleted by delete-process.  (Bug#13546)

 src/w32.c (sys_socket, sys_bind, sys_connect, sys_gethostname)
 (sys_gethostbyname, sys_getservbyname, sys_getpeername)
 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
 make sure errno is set to an appropriate value.  (Bug#13546)
 (socket_to_fd): Add assertion against indexing fd_info[] with a
 value that is out of bounds.
 (sys_accept): If fd is negative, do not set up the child_process
 structure for reading.

The bug was reported for AIX before today's changes.
I reproduced the problem on Fedora 17 x86-64 when setting
GC_MARK_STACK by hand, and I presume it occurs with default
configurations on HP-UX and Unixware.
Trunk fix on 2013-01-14 by Dmitry Antipov <dmantipov@yandex.ru>:
Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
* eval.c (eval_sub): Protect `form' from being GCed before its
car and cdr becomes protected with the backtrace entry.

Fixes: debbugs:13650

* configure.ac (DATA_START, DATA_SEG_BITS): Set to 0x20000000 on AIX.
(GC_MARK_STACK): Do not set to GC_USE_GCPROS_AS_BEFORE, as that
runs afoul of some other bug in Emacs, and the default value
GC_MAKE_GCPROS_NOOPS has been tested and works.
* src/lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
Fix bug introduced in 2012-07-27 change.  DATA_SEG_BITS, if set,
was #undeffed earlier, so it cannot be used as a macro here.
Use the constant and not the macro.  Tested on AIX.
* src/unexaix.c: Revert 2013-02-11 and 2013-02-12 changes to this
file.  They're almost surely OK but we're just before a release so
we should avoid changes unless they're clearly needed.  Instead,
make the following minor change:
(ADDR_CORRECT): New macro.

Fixes: debbugs:13650

(goto-address-fontify-region): Use them instead of narrowing, so
syntax-ppss has access to the whole buffer.

forward-sexp movement in header documentation.
(python-nav--forward-sexp): Behave like emacs-lisp-mode in
comments and strings (GH bug 114).

Fixes: debbugs:13642

defun detection.

Fixes: debbugs:13618

 src/w32proc.c (new_child): If no vacant slots are found in
 child_procs[], make another pass looking for slots whose process
 has exited or died.

 src/w32.c (sys_pipe): When failing due to file descriptors above
 MAXDESC, set errno to EMFILE.
 (_sys_read_ahead): Update cp->status when failing to read serial
 communications input, so that the status doesn't stay at
 STATUS_READ_IN_PROGRESS.

With this, it should be as good as it was in 23.3, though it's
still pretty bad: the dumped emacs does not run.  See Mark Fleishman in
http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
* unexaix.c (start_of_text): Remove.
(_data, _text): Declare as char[], not int, as AIX manual suggests.
(bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
(orig_load_scnptr, orig_data_scnptr):
Now off_t, not long, since they are file offsets.
(make_hdr): Use _data, not start_of_data ().
This is the key part of the fix.
(make_hdr, unrelocate_symbols): Use off_t for file offsets.
(unrelocate_symbols): Cast pointers to intptr_t, not to ulong.

Fixes: debbugs:13650

This ports to compilers that optimize the external declaration
'int x = 0;' as if it were 'int x;' to shrink the executable.

* doc/lispref/keymaps.texi (Scanning Keymaps):
Remove obsolete sentence about meta characters; this changed in 22.1.
