This is not acceptable.

If you change the behaviour in such a way that the main use case -- and
probably the only relevant one at that -- doesn't work anymore, you
could just as well rip it out alltogether...

Well, not knowing how this stuff is handled, I can't tell: is it really
not possible to implement proper wildcard matching of more than the
first component efficiently? It's hard to imagine why an explicit '*'
should be so much more troublesome than the implied one in the original
