BTW, maybe the generalization is to replace the "completion-predicate"
and the "command-modes" into a function that returns a *score*, with
some convention where a score lower than X means the command can't
possibly work, and score lower than Y means the command is too unlikely
to be useful to be worth listing, a score higher than Y means that the
command has a special affinity with the current situation (like "written
for the current mode"), ...
