Could you rename --force to e.g. --allow-dirty-working-copy so it's clearer what's being allowed?

I like that config option and I don't want to lose it. I was even hoping it would be on by default some day.

IIUC, the new behavior is to require --force if there are uncommitted changes, whether you're uncommitting one file or all. I was actually surprised that it used to be allowed to uncommit specific files on a dirty working copy. I like the new consistency more.

I think the --force option should be equivalent to the existing config. How about we just add `and not opts.get('force')` to the existing condition on line 159? I'd also prefer to drop the `not pats` from that condition, but that can (and should) be in a separate patch.
