Probably good to put a work-around here, or actually a  
how-to-work-with-partcombine.

The original example is probably simplified from a situation where we need  
two versions of the note: one for the part and one for the score.   
Conceptually, these happen at the same time, one in the player's part, the  
other in the score, so we should write parallel music
    << \tag#'part{e4\upbow} \tag#'full{e4^"2nd vln"} >> f g a

Whenever I use \tag to select an option from a set, I put the options in <<  
> > like this because I get very confused by the output if I accidentally  
make one option longer than another.
