Upstream makefile has got DOS line endings. These are present in the patch committed to g.g.o but are absent in the main-tree version. Hilarity ensues.

Hilarity ensues. git has frustrating default behaviour where it’ll silently strip these on commit. I can never make sense of, or remember, the toggle needed to fix it but I think it was autocrlf. Huge pain in the arse when doing games in particular which has loads of these!
Git itself is fine here (for me anyway - I've had core.autocrlf=input in my ~/.gitconfig for years), the problem is that we cannot rely on this particular behaviour having been configured on the side of things handling the synchronisation of the main tree with the g.g.o repo. Will just use sed instead.

If that were the case, it would be a rather serious infra bug.
(In reply to Sam James from comment #7) > It should also change the commit hash, I think? No, it does not - Git handles CRLF conversion between the work tree and the local repo, and whether the conversion is to be performed or not is handled by Git attributes. Let's take further discussion on this to IRC, though.
