Include Squash patch

[alexanderadam]

Right now Marge doesn't respect the squash-option, right?

Would it be possible to include this feature?

Thank you for bringing this up. It's interesting, because we have some projects where we do enforce squashing, but we haven't had any problems yet. Have we just not had any case where squashing was really needed? Or is this just needed in the case where Marge Bot actually checks out the repo etc? 🤔

In either case, if you would like to provide a PR against this repo with the changes we can probably get it merged.
