Anyway: Thanks to both of you (Jean and David); I'm a bit swamped at 
the moment and have to postpone further work on this, but will 
definitely follow the directions you gave me.

I'm not sure what you mean by "working" on this (writing .ly code
for yourself, or writing a patch for LilyPond?), but
Global_context::add_moment_to_process strikes me as a function
for which a Scheme interface could make sense.

I'm not sure if this would require a regtest, but instead of writing
one, you could port, say, Measure_grouping_engraver (which is rather
simple) to Scheme.
