For each occurence of =~ in a zwgc.desc that is exercied, we are
the output
in regcomp [Ff]rom:
(or whatever the expression is). In other words, errbuf is the empty
string. The zwgc.desc seems to be working properly as far as I know,
but I haven't looked deeply into it. I am not going to persue this
one. This is the patch I have used. This patch is wrong, of course,
but it serves to show you were in the code I'm seeing this behavior.
BTW, I've never seen the regexec print statement -- only the regcomp
one, but I'm not taking any chances. :-)
