[RFC/PATCH 1/4] replace: refactor command-mode determination

The git-replace command has three modes: listing, deleting, and replacing. The first two are selected explicitly. If none is selected, we fallback to listing when there are no arguments, and replacing otherwise.

Let's figure out up front which operation we are going to do, before getting into the application logic. That lets us simplify our option checks (e.g., we currently have to check whether a useless "--force" is given both along with an explicit list, as well as with an implicit one).

This saves some lines, makes the logic easier to follow, and will facilitate further cleanups.
