>Description:
	When ssh calls xauth to get the X11 authentication token for the
	current display to pass to the remote end it invokes it with a bogus
	trailing "." argument.

	
>How-To-Repeat:
	ssh -X -v -v <host>
	and note the:
	debug2: x11_get_proto: /usr/X11R6/bin/xauth  list :0.0 . 2>/dev/null

	
>Fix:
	Apply the following.  This has been submitted to the openssh
	bugzilla.
