Absolutely great, Glenn!

An obvious follow-up observation: The patch that was applied was for
Luc's option #3, but it seems to me that the honest solution to the
problem with timers is his option #2, to put the fix in timers. Was that
ever done?

I'm guessing a decision at some point was made not to pursue Luc's
option #2 because the emacs documentation for timers[1] says, "If a
timer function calls functions that can change the match data, it should
save and restore the match data. See Saving Match Data". Reconsidering
that decision could be of benefit emacs-wide.

Attached is a new version of the patch, with the 'save-match-data'
restored. Thanks again, Glenn.
