pregsub()

[Alexei Kosut <ak...@organic.com>]

I've added a pregsub() to util.c. It's based on the regsub() in Henry
Spencer's AT&T V8 regexp package, though different; it uses pool-allocated
strings instead of static length ones, and uses $ instead of \ as the
substitution character.

A simplified example of use:

regex_t *preg;
regmatch_t pmatch[10];

... preg = pregcomp(p, pattern, cflags)

... regexec(preg, stringtomatch, preg->re_nsub + 1, pmatch, eflags)

... pregsub(p, stringtoexpand, stringtomatch, preg->re_nsub + 1 , pmatch) 

...

Hopefully, it will be useful.
