Ed Kellett 57fbf05388 Fix a corner case of superset matching
The algorithm we're using gets stuck if it has a ? and can only see a *
to feed to it, even if it could skip over that * and consume a character
following it. Remedy this by rearranging the input so * always precedes
? in runs of wildcards, so when we're matching ? we know we can skip
things.
