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.

# Dummy extension that adds a delay after acquiring a lock.

# This extension can be used to test race conditions between lock acquisition.
