how to remove \RemoveEmptyStaffContext "up the chain"?

[Kieren MacMillan]

Hello all,

I've got a situation where one of my \include files contains a  
\layout { \context { \RemoveEmptyStaffContext } }.

99% of the time, I want this to happen. However, in a few  
circumstances — especially when engraving/editing, but also for a few  
specific pieces in final form — I want all of the functionality of  
that \include file *except* the \RESC. Is there some way I can do  
that from the main file (i.e., where the \include is called)? I'd  
rather not have to define two different files (one with \RESC and one  
without)...

Thanks,
Kieren.
