I have a quick thought.  What about creating a new grob named
CrossVoiceSlur, which would be identical to Slur in all ways except
that its engraver, Cross_voice_slur_engraver, would be placed in Staff
context by default?  This way, one could use either normal or
cross-voice slurs without messing things up.

What do you think?  I don't intend to go into a detailed discussion,
since we're focusing on releasing 2.18, but i'd just like to know
whether you consider this idea feasible or not.

best,
Janek
