It already says "if -pedantic is used with -Wformat, warnings will be
given about format features not in the selected standard version".  This
includes various pointer type mismatches that the C standard doesn't
permit for variadic functions, but which most implementations (and the
Single Unix Specification) permit, as well as the obvious cases such as
additional format specifiers.
