That said, I think it would be even nicer to print the flags that appear in the
command-line (or pragmas) that triggered this warning, instead of the flag that
controls it. So here it will print [-Wpedantic,-Woverflow]. Although we now
record the relations between the flags explicitly in the *.opt files, there is
no explicit structure that allows following the chain of dependencies.
