[Holub's verbose implementation of ad-hoc regex omitted]

Hi Gordon, Holub's regex stuff is old hat. A PD implementation of all of
this + more in a package that is a clone of BSD regex library was posted to
this net around 1986. A much more advanced [read proper] and influential
implementation of regular expression package by Henry Spencer was also
posted around that time, and has been in heavy use ever since. I think you
may be much better served by one of these packages in your programs.
