Okay, I now took a look at the code and in Tuplet_number::print, there is a 
hardcoded check that kills the tuplet number if the tuplet "does not take up 
any time". In my eyes, this is wrong, since then there is no visual 
indication of a tuplet and the timing appears totally wrong (e.g. three 
dotted quarter notes in a e/4 measure!).

Attached is a patch, which fixes this problem by removing the check for 
zero-length in the tuplet number (but of course the tuplet bracket should not 
be shown for single-note tuplets).
Since the tuplet number uses the positions calculated by 
Tuplet_bracket::calc_positions, I removed the check there, too. 
Okay to apply?

I'm also attaching a simple example to show the new output. The only 
difference to the output without the patch are the "6" and the "3" in the 
first measure, of course.

Cheers,
Reinhold
