I dunno. As ugly as the "%s" thing is in the source, at least it doesn't
change the output. Not that an extra space is the end of the world, but
it seems like it's letting the problem escape from the source code.
Do people still care about resolving this? -Wno-format-zero-length is in
the DEVELOPER options. It wasn't clear to me if that was sufficient, or
if we're going to get a bunch of reports from people that need to be
directed to the right compiler options.
The problematic code just hit 'next', so I suppose we'll see soon (OTOH,
the real test is when it get shipped as part of a release).
