I'm failing to see how it differs from regsub() which already does the

Thanks,

Mostly just convenience. It is possible to accomplish the same thing
using something like
`'regsub(".*(mypattern).*","\1")'`, but you need to remember to include
the ".*" on both sides.
I also suspect (although I haven't benchmarked it) that regmatch would
perform better than the
equivalent regsub.
That said, I do recognize that this doesn't add any completely new
functionality, and I will not
be offended at all if you don't think it is worth merging.
