vc-delete-file
vc-diff
vc-dir
vc-dir-...
is simple to compute algorithmically (string processing). It doesn't
do what you want, obviously, but it sure reduces the visual clutter.
Another algorithmic approach would be to mark each symbol defined in a
keymap with the property 'completion-keymap and the keymap (list of
keymaps). If none of the keymaps in which a symbol is defined are
currently active, filter the symbol out. Heck, maybe the property is
a premature optimization; perhaps which keymaps bind the function and
whether they are active can be done sufficiently quickly.
