Feature request: different shaped stems for half notes in tabulature

[Till Rettig]

Hi,

there has been complaints on the German lilypond forum about the stems 
of half notes in tabulatures: half notes and quarter notes look the same 
in pure tabulatur notation, if there is no traditional note line above 
specifying the rythms. A user posted a picture of a tabulatur featuring 
a half note with a triangular stem to distinguish it from the quarter 
note, see a picture:

Can this be added to the tracker?

Greetings
