I think it would probably not break anyone if the new executable name
were sufficiently distinctive -- e.g. starts_with (strrchr(argv[0],
'/'), "git-upload-pack-protocol-v2"). But it would make custom
executables a bit more complicated for the future.
I guess it is better to have silly source code but clean binaries than
clean source code but silly user-visible rules.
