- * Wildcard matching!
- *
- *  Iteration 1)
- *   Slow, horrible, etc.
- *	Iteration 2)
- *   The vastly available 'public domain' one
- *	Iteration 3)
- *   ZNC's, thought to be faster than ours, but it turned out that we could do better ;-)
- *	Iteration 4)
- *   Largely from work by peavey and myself (w00t) :)
- *	Iteration 5)
- *   peavey: Fix glob scan similar to 1.1, but scan ahead on glob in inner loop to retain speedup
- *   this fixes another case which we forgot to test. Add early return for obvious fail condition.
