Suppress Staff.shortInstrumentName printing for parts?

[Nick Didkovsky]

Hello

I am using Staff.instrumentName and Staff.shortInstrumentName. Works 
great for full ensemble scores. As expected the first system shows the 
long name and subsequent systems show short name.

However I then print parts and get undesired effect of having a part 
with the long name on the top line and the short name on every 
subsequent line. Of course I don't want the short name to be printed at 
all when I print a part.

Other than editing the staff's .ly file after printing the full ensemble 
score and removing the short name for part printing, is there a switch I 
can set in the part printing file to suppress short name printing?

Something I can specify before the following block for example, which 
prints one of my staves, that would suppress short name printing?
