I'm fairly sure it is much less common than the narrow versions,
we don't even handle wprintf and wscanf attributes.
Tracking not just char strings, but also wchar_t (or either char, or
wchar_t) would complicate the pass somewhat, but I'm more worried that it
would not be stressed enough in real-world code and thus would be less
tested than would be desirable. Plus it is very premature when none of the
wcs* builtins are actually handled in builtins.c and we don't have
infrastructure for that.
