I had a look at my reference books, but couldn't find any good
examples f o arpeggii. I don't like the shape of the arrow. Either
the arrow should be disconnected from the arpeggio like this

(i've seen the 2nd version.), or the arrowhead should be calligraphed,
to match the design of the squiggle.  I actually prefer the last
solution, but it will need more work. Perhaps Jan can look into Stone,
in the chapter on piano notation.

I'll integrate the patch if you change the current design into either

this is a little clumsy. You can simple make horizontal and vertical
lines using Lookup::filledbox (). It's probably easier to code if you
make a separate function for the brace molecule.
