tremolos shorter than a quarter

[Peter Lutek]

is there any plan to support tremolos shorter than a quarter?

i.e.  \repeat "tremolo"  2 { c32 e32 }

i've had occasion to need them, but they generate a warning and end up 
looking like squished-together quarter tremolos with no beam between the 
stems. i'll have to hack a beam somehow for now.

-p

btw - 1.9.8 is excellent. the simplified syntax and new octave 
conventions are quite welcome! it took me a while to clean up after 
running convert-ly on the large score i'm working on, but it was 
definitely worth it. and it's a big relief to be able to split beams 
over lines with only one note hanging on either side of the split. YAY!
