It seems that GNU man itself varies. The GNU man on the debian linux
system I have access to at work prints:
What manual page do you want?
in response to -w with no argument and has no -W option. Note that it
does return an exit code of 1 though so we can still use man -w if we
check the exit code.

That must be specific to your linux distribution as opposed to GNU man.

That's probably the best approach as long as we don't find a system that
breaks it.
