I wasn't aware I was "doing it wrong" with this, I saw that coeurl 0.3.0
failed on core-updates but a bump to 0.3.1 fixed the build, and it could
go to master also. Similar story with working to remove
fontforge-20190801 which no longer built on core-updates. I figured that
applying the patch to both branches would make it easier to merge master
into core-updates since there would be less drift between the two.

What is the correct way to apply a patch to multiple branches?
