I think Branden was asking why you might wish to use a wildcard in
this situation.  A better example might be a game such as Nethack
which can take a long time to finish but whose save files are
generally incompatible across upstream versions.  (Another possibility
would be an application taking some sort of binary plugins which are
incompatible across upstream versions; I haven't been able to find a
concrete example, though.)
