Thanks. The point of checking against fnmatch is to make sure that
wildmatch does not divert in behavior from fnmatch. For some corner
cases that behavior is undefined, I think it is ok for different
fnmatch versions to behave differently.

But some of failed tests make me worry about fnmatch. compat/fnmatch
for example does not match '**/foo' with '/foo' (it does '*/foo' with
'/foo'). 'A' is matched with '[[:digit:][:space:][:upper:]]' but not
'[[:digit:][:upper:][:space:]]'. Perhaps we better off convert git to
use wildmatch only to keep matching behavior more reliable. wildmatch
does not support non-FNM_PATHNAME mode, but that should be easy to
fix. The only downside I see is fnmatch may support locale while
wildmatch does not.
