   One .sym65 file has constants for the $Cxxx locations for all Apple II   
   systems.  I had created another for the $E0/Cxxx constants, with names like   
   "KBDSTRB_GS".  Apparently I forgot that the I/O locations are mapped into   
   banks $E0 *and* $E1.  The update    
   creates mappings for both banks, with names like KBDSTRB_E0 and KBDSTRB_E1.   
      
   It's possible to have a single file with a MULTI_MASK statement (which is used   
   to define I/O locations that are mirrored across multiple addresses), but I   
   thought the output looked better with explicit "_E0"/"_E1".  SourceGen still   
   lacks a mapping for $   
   01/Cxxx, but I haven't seen anything reference those in 16-bit code.
