[Bug] test applet does not work as before

[Harald Küthe]

Hello list, 

we discovered that the busybox 1.6.0 test applet does not behave as before (and as e.g. a debian system)

Debian 3.1:
if [ ! "a" = "a" ]; then echo "unequal"; else echo "equal"; fi
equal

busybox-1.5.1
/ # if /bin/busybox-1.5.1 [ ! "a" = "a" ]; then echo "unequal"; else echo "equal"; fi
equal

BusyBox v1.6.0 (2007-06-24 23:06:12 CEST) Built-in shell (ash):
/ # if [ ! "a" = "a" ]; then echo "unequal"; else echo "equal"; fi
unequal

Regards
Harald
