The era of automatic backports is over :(

@lysnikolaou Could you make the backport using cherry_picker?

I guess that's because of the different filenames?

Not really, my git was smart enough to do the remapping in previous backports

Yes, but Parser/parser.c existed in previous versions as well, right?

Yep, but git knows the story of that file, the same way it will do if you do git log FILE --follow: it will only show you the story of FILE across renames even if it substituted some other file that had the same name before (there is an heuristic that you can tune for when git thinks you delete + create Vs when it thinks you modified).

Oh okay, didn't know that.
