I guess I could use opt_code instead of bool, but
1) I think we still want not to bother with warning_suppressed_p at all for
-Wformat*, for one there are various warning options affected, and as I said,
it isn't warning at all, it is looking for the argument value
2) passing that for -Wnonnull is deferred for later
