So, if fooa does exist and foob not, is this then supposed to return
both "fooa" and "foob", or just "fooa"?
glob("foo{a,b}")
(I get them both anyway...)
If it should be just "fooa", then I'd like to mote that solutions based
upon this trick would be disqualified, because they won't work on all
reasonable systems. :-)
