I don't have a preference on which direction we go, but yes, right now
we are in an awkward middle ground. We should do one of:

  1. Drop -Wno-format-zero-length from DEVELOPER_CFLAGS and make sure
     future patches to do not violate it.

  2. Declare warning("") as OK.

I still think the warning is silly, but (1) has value in that it
produces the least surprise and annoyance to various people building
Git.
