Sorry if I was unclear. I was stating that the condition udner which the
check runs is now difference. Previously we checked `opts->pathspec.nr`,
but now `checkout_paths()` is also entered for '--patch' without any
path spec.
Having a closer look, it seems to be okay. Because in patch mode, each
of the combinations is already rejected before in `checkout_paths()`.
It still might be good to have a sentence in a the commit message, since
the guard did change and the reasoning why that is safe is not so
obvious.
This does however change the precedence of the error messages:
$ git.master restore --staged --theirs --merge foo
fatal: git checkout: --ours/--theirs, --force and --merge are
incompatible when checking out of the index.
$ git.patch restore --staged --theirs --merge foo
fatal: '--ours' or '--theirs' cannot be used with --staged
This seems okay to me, not sure if we have tests to validate this
behavior.
