Log Message:
-----------
Our interface code for Spencer's regexp package was checking for regexp
error conditions during regexp compile, but not during regexp execution;
any sort of "can't happen" errors would be treated as no-match instead
of being reported as they should be. Noticed while trying to duplicate
a reported Tcl bug.
