You'd think; but based on the sheer number of -Wformat warnings
(~450), I'm not so sure.  At least with this patch they're "above the
fold."

The kernel also has its own format flag extensions, and does not
implement %n (for good reason), so it's better to be explicit than
imply posix or glibc compat.
