Completion_heads_engraver doesn't work on rests. Is this a bug

Rests are engraved by the Rest_engraver and
Multi_measure_rest_engraver, which means that pulling stunts with
Note_heads_engraver will have no impact on that.
So, while it's not a bug per se, having a Completion_rests_engraver is
quite a feature request, to the point of making
Completion_heads_engraver usable at all.
Thanks for the example.
