Huh. I was going to say how git-apply(1) probably uses patch(1) internally after doing some preprocessing on the patches it's given, but, on checking it, it seems it doesn't. Using strings(1) on the git executable turns up "%s/patch", which made me suspect the executable path was interpolated, but `git diff ...@~ | strace -fe trace=execve git apply` on an arbitrary repo turned up nothing, and I couldn't find "%s/patch" in git's source.
