hi again,
i'm using cmn to manuscript one of my own pieces now, and i'm noticing 
something strange about glissando. for an upward gliss, the line begins 
at the top of the start note's notehead and ends at the bottom of the 
destination's notehead - which would be fine, except that in glisses of 
one step up (a line to its adjacent space, say) the line itself slants 
down. the opposite case happens with downward glisses.

(cmn (free-expansion-factor 2.5)
   (e4 q (begin-glissando))
   (f4 q (end-glissando))
   (g4 q (begin-glissando))
   (f4 q (end-glissando)))
it really seems like the gliss line should be drawn from the center of 
the notehead in either case. how would i go about changing this behavior?

... and thanks very much to Anders for his help with the generic bracket 
object. the stem-direction compensation fixed the problem i was having 
with that.
