This was all well and good until I found that I had two metronome 
markings occurring at the same time.  Lily doesn't like that any more 
than two rehearsal mark appearing at the same time.  The odd score I'm 
working on has two time signatures going on at the same time.  One is in 
1/4 and the other is in 5/8.  I need to print both

4 = 53 and 4 ~ 4. = 53

...on separate staves.  I'm thinking I'm back to my polyphonic solution 
above.

(Is the snippet repository off-line?  I can't get in now.)
