As Peff summarized, an earlier patch was dropped with "It is easy
for builders with such compilers to squelch the warning."  We are
reversing the course, with an updated log message like this ;-)

   The user have long been told to pass -Wno-format-zero-length, but a
   patch that avoids warning altogether is not too noisy, so let's do
   so.
