statement(s) separates point from defun.

 Don't set buffer-file-type.  Return nil.

 make-dist (nt): Adjust to changes in names of the *.manifest files.

Regenerate AUTHORS and ldefs-boot.el.

As reported by Harald Hanche-Olsen in
<http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00445.html>
the change introduces a further bug, of creating lots of zombie
processes in some cases.  Further work is needed to come up with a
better fix for Bug#8855.

* mouse.el (mouse-drag-line): Even if the line is not draggable,
keep reading until we get the up-event anyway, in order to process
the up-event for mouse-1-click-follows-link.

Fixes: debbugs:12971

 src/xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
 highlighting on the frame was cleared.  Prevents assertion
 violations when repeatedly clicking on the "Top" link of the
 "bread-crumbs" in Info buffers.

This is a backport from the trunk, consisting of:

* nt/inc/sys/wait.h: New file, with prototype of waitpid and
definitions of macros it needs.
* nt/inc/ms-w32.h (wait): Don't define, 'wait' is not used anymore.
(sys_wait): Remove prototype.
* nt/config.nt (HAVE_SYS_WAIT_H): Define to 1.
* src/w32proc.c (create_child): Don't clip the PID of the child
process to fit into an Emacs integer, as this is no longer a
restriction.
(waitpid): Rename from sys_wait.  Emulate a Posix 'waitpid' by
reaping only the process specified by PID argument, if that is
positive.  Use PID instead of dead_child to know which process to
reap.  Wait for the child to die only if WNOHANG is not in
OPTIONS.
(sys_select): Don't set dead_child.
* src/sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
as it is no longer needed.
* src/process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
no longer needed.
(record_child_status_change): Remove the setting of
record_at_most_one_child for the !WNOHANG case.

Fix a race condition that causes Emacs to mess up glib (Bug#8855).
This is a backport from the trunk.
The symptom is a diagnostic "GLib-WARNING **: In call to
g_spawn_sync(), exit status of a child process was requested but
SIGCHLD action was set to SIG_IGN and ECHILD was received by
waitpid(), so exit status can't be returned."  The diagnostic
is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
The real bug is a race condition between Emacs and glib: Emacs
does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
so that glib can't find it.  Work around the bug by invoking
waitpid only on subprocesses that Emacs itself creates.
* src/process.c (create_process, record_child_status_change):
Don't use special value -1 in pid field, as the caller now must
know the pid rather than having the callee infer it.  The
inference was sometimes incorrect anyway, due to another race.
(create_process): Set new 'alive' member if child is created.
(process_status_retrieved): New function.
(record_child_status_change): Use it.
Accept negative 1st argument, which means to wait for the
processes that Emacs already knows about.  Move special-case code
for DOS_NT (which lacks WNOHANG) here, from caller.  Keep track of
processes that have already been waited for, by testing and
clearing new 'alive' member.
(CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
now does this internally.
(handle_child_signal): Let record_child_status_change do all
the work, since we do not want to reap all exited child processes,
only the child processes that Emacs itself created.
* src/process.h (Lisp_Process): New boolean member 'alive'.

 src/xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
 between bpos_covered and bpos_max.  This fixes cursor display when
 several display strings follow each other.

Check for `use-region-p' if `interactive' is non-nil.
(dired-unmark, dired-flag-file-deletion): Add optional arg
`interactive'.  Call `dired-mark' with the arg `interactive'.

 src/.gdbinit (pgx): If the glyph's object is a string, display the
 pointer to string data, rather than the value of the string object
 itself (which barfs under CHECK_LISP_OBJECT_TYPE).

Patch by Christopher Schmidt <christopher@ch.ristopher.com>.
(wdired-finish-edit): Add marks for new file names to
`wdired-old-marks'.  Restore marks using `dired-mark-remembered'
after `revert-buffer'.
(wdired-do-renames): Remove calls to `dired-remove-file',
`dired-add-file', `dired-add-entry'.

 src/indent.c (Fvertical_motion): If the starting position is covered
 by a display string, return to one position before that, to avoid
 overshooting it inside move_it_to.
