Hi Harm,

Is there a reason to reset variables in 'finalize'
methods like this?

I've done without so far and never had any
problem; engravers in scm/scheme-engravers.scm
only do it when you are their author ;-)

Just curious.

Thanks,
Jean

Well, I seem to remember that there was a problem, if a
custom-engraver was consisted in various files all compiled in one go
like
lilypond file-1.ly file-2.ly.
Some bleed over, iirc. I didn't test recently, though. It doesn't hurt
to reset the variables, imho.

Cheers,
   Harm

Ok, thanks! I'll do some tests later on today.
