I noticed the problem while working on a user-request wanting to use
the same predefined stuff for putting in one staff _and_ in separate
stuffs.
Using direction-modifiers wouldn't be feasible for that purpose.

sometimes behaves differently from Fingering.

Ofcourse those two engravers are involved, depending on the input.
Doesn't makes it easier...

Using `tag' is possible, yes, but I don't use it very often, it's more
last resort.
