Update of /home/or/cvsroot/tor/src/or
In directory moria:/tmp/cvs-serv23218/src/or

Modified Files:
	directory.c 
Log Message:
Directory authorities should go to the proper authority when asking for a networkstatus, even when they want a compressed one.  (Also, bullet-proof the logic in case we ever accidentally request a networkstatus for a non-authority.)
