left-margin and shortInstrumentName

[David Stocker]

Hello everyone,

I'm noticing that when I give instruments a shortInstrumentName in a 
score, that the short name doesn't respect the left margin the way the 
instrumentName does. Is there a way to make this happen? Or, is there a 
way to tell LilyPond to print the page margins? That way I could get the 
result I'm after using short-indent in the \paper block. As it is, I can 
fudge it, but I'm rather particular when it comes to precision.

Thanks,

David
