BTW, I have a patch based on Steven's one that is almost working and for simple
strings handles a location+offset. However, there are several issues:

* Cases like:

1: const str[] = "something %d";
2: printf(str);

will report a location at 2 plus offset of %d, not nice.

* I didn't transform the most obscure format warnings. Some of them have no
easy location at hand and others I simply don't know what we want to point at.

* It would be extremely nice to update the testsuite to check the locations are
correct. This is unfortunately a lot of boring work, so if I cannot get help to
do this, I hope it is not a pre-condition for approval.
