TupletNumber regression

[John David Duncan]

Hi,

I have an example where 2.15.38 does a worse job than 2.14.2 at  
placing a TupletNumber.

I suspect it's related to a forced \stemUp, because the number might  
be in the right place if the stem were going down.

How should I submit my example ... in email here?  In an issue reporter?

Thanks,

JD
