Yeah, I'd definitly want a prompt or be required to set a flag
when checking out to an existing repository as I've already
cloned into existing directories multiple times by accident.

I guess a new flag would be the most obvious thing to do here. No
idea though what this flag should be called.
`--allow-clone-to-existing-dir` is really long,
`--force-existing` may be mistaken for requiring an existing
directory. Any ideas?
