More than I.  I can understand your disappointment that 
file-dialogue "file patterns" have such a rudimentary
syntax; I speculate with considerable confidence that
the authors acted with sh as the model most in their
mind.  You're quite right, Laura, that the elements are
at hand to allow you to construct your own variant.  If
the history of getOpenFile truly interests you, act 
quickly:  while we can get to the authors now, it won't
be many cycles more before their memories and records
senesce irretrievably.
