git-xargs should open PRs even if it did not commit any changes

I think, git-xargs should always open PRs even if the given command did not change anything locally or if the push returns already up-to-date.
The reason why I use your great tool, is that I want to merge some changes in to my main-branch. I don't care if the tool does these changes, commit them and push them to the branch I passed to the tool, or if these changes already exists in the remote branch, as long as a PR is opened so I can merge my changes into main.
