[SunHELP] $DISPLAY for root

[David Baldwin]

AHA!!!
I should have seen that
But, alas, the error still occurs.
I am using bash for users and sh for root if it makes any difference.  I
did try it as a regular user also.

Looks like it needs a finishing fi...

# Set the DISPLAY global environment variable.
if [ ! "$DISPLAY" ]; then
       set -A DISPLAY $(who -um)
       DISPLAY=3D${DISPLAY[$((${#DISPLAY[*]} - 1))]}
       DISPLAY=3D${DISPLAY%:0.0}:0.0
       export DISPLAY
fi

... tested with bash and ksh.
