* lisp/align.el: Use lexical-binding.
(align-region): Simplify accordingly.

Add rudimentary inferior shell interaction
* lisp/progmodes/sh-script.el (sh-shell-process): New buffer-local variable.
(sh-set-shell): Reset it.
(sh-show-shell, sh-cd-here, sh-send-line-or-region-and-step): New
commands (bound to C-c C-z, C-c C-d, and C-c C-n).
merge from trunk
* process.c (allocate_pty) [PTY_OPEN]: Set fd's FD_CLOEXEC flag.

We can't portably rely on PTY_OPEN doing that, even if
it calls posix_openpt with O_CLOEXEC.
merge from trunk
Port close-on-exec pty creation to FreeBSD 9.1-RELEASE.

* configure.ac (PTY_OPEN): If posix_openpt with O_CLOEXEC fails
and reports EINVAL, try it again without O_CLOEXEC.  This should
port PTY_OPEN to FreeBSD 9, which stupidly rejects O_CLOEXEC.
What were they thinking?
merge from trunk
Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE
and GC_MARK_STACK == GC_USE_GCPROS_CHECK_ZOMBIES.
* alloc.c (toplevel): Remove unnecessary nested #if...#endif.
(mark_maybe_object) [!GC_MARK_STACK]: Define to emacs_abort
to shut up compiler in mark_object.
(dump_zombies): Convert to global and add EXTERNALLY_VISIBLE.
merge from trunk
Auto-commit of generated files.
merge from trunk
* lisp/emacs-lisp/pp.el (pp-eval-expression, pp-macroexpand-expression):
Use read--expression so that completion works again.

Imported EIEIO test suite from CEDET upstream

* automated/eieio-tests.el, automated/eieio-test-persist.el:
* automated/eieio-test-methodinvoke.el: EIEIO tests from CEDET
  upstream.  Changed to use ERT.
merge from trunk
* callproc.c: Fix race that killed background processes.

(call_process): New arg TEMPFILE_INDEX.  Callers changed.
Record deleted process-id in critical section, not afterwards.
Don't mistakenly kill process created by a call-process invocation
that discards output and does not wait.
merge from trunk
* lisp/calendar/timeclock.el: Minor cleanups.
(timeclock-ask-before-exiting, timeclock-use-display-time): Use `symbol'.
(timeclock-modeline-display): Define as alias before the actual definition.
(timeclock-mode-line-display): Use define-minor-mode.
(timeclock-day-list-template): Make it a function, add an argument.
(timeclock-day-list-required, timeclock-day-list-length)
(timeclock-day-list-debt, timeclock-day-list-span)
(timeclock-day-list-break): Adjust calls accordingly.
