Tremolo / tuplet

[Zbyněk Burget]

Hi,
I've small problem
I've following bar:

c4-. \times 2/3 { \repeat "tremolo" 3 c8 } c4-. \times 2/3 { \repeat 
"tremolo" 3 c8 }

so-called tremolo is "in tuplet". But tuplet numbers are not printed.
Is any way to "visible" tuplet numbers?

My idea was some as  { c8-3 }, but tuplet numbers are italic and 
fingerings are bold :-(

Thanks, Zbynek
