rust-filepatterns: add comment about Windows path handling...

rust-filepatterns: add comment about Windows path handling As I replied to the Phabricator message, this is wrong. And I even suspect it wouldn't compile because of multiple type mismatches. I think, in Rust where type system is rock solid, we can live with UTF-8 strings except for the bottom storage layer and the top UI/command layer. We'll still have to get around undecodable characters not to be lost, but I think it's okay to drop such filenames from match result if they don't match in UTF-8 world, not in Latin-1 world.
