Not really, although your approach should work in most cases. For Accidentals,
though, the code that places a tied accidental after a line break isn't
accessible from scheme (it lives in lily/accidental.cc, in the print
function).
Anyway, here's a patch (to be applied with "git am") that implements a new
property, 'hide-tied-accidental-after-break, in the Accidental grob. I'll
apply it soonish unless there are complaints.
Cheers,
Joe
