Attached, is version 1.4 of expand_regex.pl. Notable changes are:
- improved handling of bracketed regex's in situation like ( ( )? ) where the previous version did not deal with nested balanced expressions correctly - added a -lint option which will run the most helpful warning options. - added -warn=b for those who want to check that their patterns begin and end with '\b'. I plan on only making small bug fixes at this point, but will work to ensure that the latest version is on either the exit0 or SA Wiki page. A more robust program would have to understand and parse the full syntax of a Perl regex, and that is beyond the scope of this simple tool. Hopefully, the current level of function will prove useful for now.
