I assumed a C-x o here.  ;-)

I find myself on L96.  I can't reproduce this error, neither on a tty or
in X windows.  I tried repeating the C-M-f, so that the C-p C-e brought
point to just after "RWINFO_PROPERTY_COUNT" and typing a comma there.
That still didn't signal an error.

I've just committed the current state of the fixes to the Emacs-24 branch
at savannah, for the pretest next weekend.

Thanks again for all the input.
