Hello Eli.
I must admit, I didn't check thoroughly, so I can't be sure it doesn't
break the font-locking of quotes in other places.
I have come up with the following way of testing a new regexp:
Step 1: In Info files that come with Emacs, search the original
regexp and the new regexp for all the matches. Compare both results,
discarding the insersecting values (IOW, discard the matches for which a
new regexp wouldn't introduce new behavior).
Step 2: Based on the previous, analyze each new behavior, to see if a
new regexp does the right thing, or not.
Step 3: Accept, adjust or discard the regexp, accordingly. If not
accepted, go back to Step 1 for a new iteration.
Provided the final regexp doesn't break display in other places (and
of course, improves the current behavior), would the procedure
I've just described be enough to trust a change?
