Hmm, from my experiments, bash doesn't show a/b as matching the
pattern a/**/b ...

Although I can see Vinay's point, that ** is not useful syntax
currently, so there's no compatibility problem. Careless use resulting
in long glob times is more of a user issue.

Having said that, this debate is *precisely* why I suggested making it
a parameter in the first place, so people can choose for themselves.
So I guess I agree with your decision :-)
