The PC in PCRE means "Perl-compatible". PCRE is *not* POSIX compatible. The
documentation clearly states that the POSIX interface is just that; it is an
API that uses the POSIX functions calls, but the behaviour of the matching
process is not altered. If you match the string 'b' against 'a?|b?' in Perl,
you get exactly the same result as PCRE.
Applying your patch would give POSIX-like behaviour in just this one, special
case, leaving the rest of PCRE's behaviour unchanged. This, I am sure, would be
wrong.
So, I'm sorry, but I cannot accept your patch.
