possible bug with $@ and and non-standard IFS

[JR Rothschild]

Hi,
In either version 3.1.17 (SUSE 10) or 3.2.25 (RHEL 5.3), with $DISPLAY
set to :0.0
the following script gives unexpected results.(It works with version
3.0.15 - RHEL4.6)  The echo should print out

smith:0.0

instead of

smith 0.0

#!!/bin/bash
dh=smith
oldIFS=$IFS
IFS=:
set $DISPLAY
nd="${dh}:$@"
IFS=$oldIFS

echo $nd

Thanks for taking a look at this.

JR
