yes, the current version of regex.c in gnulib originated from Emacs.

But I think there is consensus that this version should be replaced by the
regex code from GNU C Library (glibc).
That means using files available in
in subdirectory posix.

The advantage of the glibc code is that it handles various locales correctly.
(The code was written from Isamu Hasegawa from IBM Japan.)

I'm afraid that that version doesn't handle non-greedy matching.  I'm not
sure whether the glibc developers would like to see such an enhancement.
It's best to contact them, perhaps via

A cheeky question: when you want perl-like features in your regexes,
wouldn't pcre match your needs better?

Have a nice day,
