It seems to only complete processes from the current terminal.  For
example, if I just do 'ps <TAB>', I get:

    % ps
    ...
    > process ID
    23620 pts/11   00:00:00 zsh
    23647 pts/11   00:00:00 zsh
    23648 pts/11   00:00:00 ps

    ...

I guess that's due to _pids running 'ps' without further arguments.
Shouldn't the command be configurable?  I'd love to have it show all
user processes (or even all processes when sudoed).

For 'kill' we already allow customizing the listing format via the
'command' style; I suppose it would be nice to support the same here.

Cheers,
