Come to think of it, why can't we introduce a wrapper script (we could call 
it xssh) instead of patching ssh itself?  Here's my suggestion:

#!/bin/sh

if [ -n "$DISPLAY" ]
then
 echo "Error: In order to enable X11 forwarding the DISPLAY variable must 
be set"
 exit
fi

ssh -X $*


Or, alternatively:

if [ -n "$DISPLAY" ]
then
 export DISPLAY=127.0.0.1:0.0
fi

ssh -X $*
