That's pretty much it for the simple syntax, although the pattern needs
explicit ^ & $ anchoring. E.g. f* should match "foo" but "*oo" shouldn't match
"foo".
There's a lot more to modern glob syntax than that though. The Git test suite
has regression tests for wildmatch() & POSIX fnmatch(). This a list of:
match <matches w/fnmatch?> <matches w/fnmatch?> <text> <pattern>
https://github.com/git/git/blob/v2.12.0/t/t3070-wildmatch.sh#L43
There's *, **, character classes etc.
