MFC rev 1.6:

Browse Source 
When removing the local domain, only do so when the result
	will be a host name.  This is matches the documented behaviro.
	The previous behavior would remove the domain name even if
	the result retained a dot.

	This fixes rsh connections from a.example.com to example.com.

This is also reported to fix rsh connections from host xxx to
yyy.example.com.
