Simple pattern fails to compile correctly

[giltayar]

If I compile('foo.txt'), it should accept('foo.txt'), but doesn't. It also does not accept('a/foo.txt').

@giltayar not using this plugin at the moment, but PRs welcome. This is happening because it expects that there's at least one negation (!somefile.txt) in the file, it should be really simple to fix but I won't have time to do it myself.
