Add a --dry-run option to branch creation that can check whether or not a branch name and start point would be valid for a repository without creating a branch.

The usage & test show that we've got --dry-run for branch creation, but not the "creation" we do on --copy or --move. The former is just a "create from source", but "move" maybe not. In any case, any reason to leave those out?
