You reviewed my patch at the time and provided feedback, and I'd
produced a revised version based on that feedback.

The heuristics in the patch I submitted almost completely eliminate
false positives, which makes my patch suitable for use without --strict.
Having a --strict version which flags *all* wrapped strings seems
potentially reasonable as well (though you'll still want the heuristic
that ignores strings ending in \n or \n\t), but I'd still like to get my
version included with the heuristics that make it suitable as a default.

Among other things, the version you submitted to Andrew will flag
multi-instruction __asm__ directives, multi-line strings printed with a
single printk, and arrays of arbitrary data expressed as strings.
