I'm afraid that is not all. The rules I've inferred:
1. No pattern will match directory tree.
2. It is only possible to match on path components.
3. If pattern contains slash it is treated as absolute.
Example for file: d1/d2/f1.c
Patterns that match:
*.c
d1/d2/*
/d1/d2/*
*/d2/*
*/*/*
Patterns that do not match but should:
d2/*
d2/
d2
d1/d2
/d1/d2
