Right. And since we only want it in command position, we should
probably put it in _command_names.

It's in builtins.yo under `bg' and `fg'.

It's `compset -q' -- and with that I can repeat the question I asked
at the time when I sent the completion-quoting-patch: currently the
`-q' option only has an effect if the word on the command line is
quoted -- should we change it to work on unquoted strings, too?

And: nothing against giving _normal (an) optional argument(s) that
will be put at the front of $words. (_normal is one of the older
functions that survived (with changes) the transition from reporting
command line words as positional parameters to the $words array we
have now; that's why nobody made it accept arguments again, I think).
