Then, let's say we have one of such options. For example, let's call
it -Wx for this example. If the behaviour is consistent with other
"group" options like -Wall, then:

-Wx is enabled by default (like now)
-Wno-pedantic does not disable -Wx (like now)

But then

-Werror=pedantic implies -Werror=x ? (to mimic -pedantic-errors)

For example, -Wmain is enabled by default but also by -Wall and
-pedantic. However, -Werror=all does not enable -Werror=main. Is this
a bug or the desired behaviour?

And even less clear case is:

-Wno-error=pedantic -Werror implies -Werror=x or -Wno-error=x? The
documentation only says that -Wno-error= does not imply anything.
