Here's how that would have looked, but it seems I'm too late.
The Makefile rules get a bit more fragile because the version files are
special and the simpler --add-file forces us to create them at their
actual place if not present, which can lead to problems (stuck version)
if we don't delete them afterwards. Avoiding that was the reason for
the more complicated version that ended up in v2.29. That fragility
could be defused by teaching GIT-VERSION-GEN about version_is_generated.
Anyway, at this point I'm OK with keeping the released version to avoid
additional confusion.
