I think: no. The Unix wildcard based patterns are usually often too
weak for more sophisticated matching -- well, from a theoretical POV
they are already in a completely different class of expressiveness. As
a result one usually always ends up with additional filtering (based
on regular expressions). So, your do already a fts(3) walk instead of
glob(3) is also just fine as the regex filtering has to happen usually
always anyway...
