bug#13623: 24.3.50; Redisplay issue with transient-mark-mode

[Lawrence Mitchell]

When using word or sexp marking commands, the active region does not
always get highlighted.

emacs -Q
M-<
M-@ # note how ";; This" is selected, and highlighted in region-face
M-@ # ";; This buffer" is selected, however, " buffer" is not highlighted

Pressing C-l at this point, correctly shows the highlighted region.

This is with:

    * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC

I'd previously updated and built on the 19th of January:

commit c5a8149837c5ed53655d4383dea3b8f29374b266

    * lisp-mode.el (emacs-lisp-mode-map): Add native profiler menu entries.


Which didn't demonstrate this behaviour, if that happens to help with
tracking the issue down.

Cheers,
Lawrence
