The format-security warning is a special case of format-nonliteral that applies when there are no arguments besides the format string. In those cases, for printf and NSLog-style functions, there is an easy fix to provide a literal format string of "%s" (or @"%@" for Objective-C), with the nonliteral string as the argument. This patch teaches clang to provide fix-its for those cases.
