When `git stash show` is given no arguments, it will pass `--stat` to
`git diff` by default. When any argument is given, `--stat` is no longer
passed by default.

When `git stash show` learned the `--include-untracked` and
`--only-untracked` options, it failed to retain the same behaviour of
not passing `--stat` by default.

This isn't necessarily incorrect since with other arguments, they're
passed through directly to `git diff` which means it wouldn't make sense
to pass `--stat` as well. With `--include-untracked` and
`--only-untracked`, they are handled by `git stash show` directly
meaning we don't necessarily have this conflict. However, this would be
unintuitive for users since the existing behaviour seems to be that if
any arguments are given, `--stat` will not be given by default.

Don't setup the default diff output format if `--include-untracked` or
`--only-untracked` are given.
