Exaggeration, sure.  But it contains a kernel of truth.

True, but not relevant unless you know which ones they are.  Offhand,
I don't, and the docstrings/source comments are less than 100%

Anyway, I've implemented a last-match-succeeded flag (for debug usage
only) and check it in match_limits and Fmatch_data (when XEmacs is
configured for error-checking).  If we catch anything that looks
relevant to GNU Emacs I'll report it here.
