__attribute__((format(printf))) doesn't seem to catch missing format
string in function call ie.
char *p = "foo";
printf(p);
vs
printf("%s", p);
Enabling -Wformat -Wformat-security warns in such case.

This should allow to early catch bugs like those fixed in
patch "Add missing format specifiers in src/error.c" sent by
Mariusz.
