Hm, gitlab says the source branch must be rebased onto the target branch. But it looks like they're the same, other than my new commit added on top of the current 9e5d54ea master HEAD. Not sure what I did wrong there or what I need to do to resolve that message (I'm still using the old git://source.winehq.org/git/wine.git repo for pulls, maybe that's an issue for some reason).
