Yes, Clef grobs are created at every barline and suicided later.
(The snippet
{
c1 c c c
}
creates *5* clefs. I simply added a printf to
Clef_engraver::create_clef to verify this.)
There is just no way to know where line breaks will be when grobs are
created, so your method is probably the only one feasible. As
wasteful as it seems, it is the way things are done with breakable
items.
So, kudos!
