To be explicit, then, the proposal is that «brokensymlink(-W)» and
«brokensymlink(-^W)» should both trigger the "no match" error?  (I.e.,
the target of a broken symlink is neither writable nor not writable.)

What should «brokensymlink(-)» do?

What would be the glob qualifier syntax for broken symlinks?
