Tab autocomplete, auto-quoting paths doesn't seem to work as in Clink 0.4.9 about clink HOT 1 CLOSED

I see. menu-complete had a problem with too much quoting. Fixing that problem accidentally introduced this problem.

UPDATE: Oh, it turns out actually this is just how Readline works. git-bash behaves the same way. The difference is that Clink used to have two match completion systems and sometimes it used its own internal one, and sometimes it used Readline, but now Clink always uses Readline.

I'll do something about this. I agree that it would be much better (on Windows, at least) to insert a quote character when using complete if any of the matches may require a quote. Because on Windows you can't use \ (backslash, space) to quote spaces, so it's very cumbersome to massage the input so that completion can continue to work after typing a space -- whereas on *nix you'd just type \ and not need to quote it at all.
