We allow /. since this would mark the beginning of a hidden folder, and enables showing hidden folders, if they're disabled by default. However the /. b definitely seems odd. I've changed the behavior such that if the current path segment contains a space, we don't return any items, but previous path segments may contain spaces.

Allowed: ~/example foo/b Not allowed: ~/example foo

Thanks for your great plugin and quick fix!

We allow /. since this would mark the beginning of a hidden folder, and enables showing hidden folders, if they're disabled by default.

This sounds reasonable, but I don't have a hidden directory or file in my root directory, and path source still brings up the completion menu, which doesn't seem to match my intuition.

Good point, we should still match on the . but we don't have a great way to do this atm. Might need #657
