2.0b1 broken macro handling

[Ethan Galstad]

This was a fun one to track down.  Basically, there was a bug in the 
macro expansion code, which resulted in the said macros being left as 
strings (i.e. "$SERVICEDESC$", "$SERVICESTATE$", etc.), which then 
got nuked by the environment an converted to "$".  Fix should be in 
CVS shortly.
