Wow, that is a bad one. If people do want "DEFAULT_GIT_PORT", they
would never write STR(DEFAULT_GIT_PORT). I wonder if we can have a
bit more clever STR() macro that catches this kind of mistake at the
compile time.
If this is worth fixing, the fix would probably be worth protecting
with a test or two, but the networking test with fixed port is not
something we can easily do without a sealed environment, so...
Thanks Michael for catching this.

Yeah, burying it in a 24-patch series is a bit unfortunate.
