Summary:                    ash - problem with expression evaluation
Description: 
with at least 1.6.x till yesterdays svn the following 
expression incorrectly evaluates to true:

if [ ! "a" = "b" -a ! "c" = "c" ];then echo true;fi

(found while modifying the initial ramdisk in the
RIP (Recovery Is Possible) Linux distribution.

The last version which seems to work OK is busybox-1.5.1.

busybox 1.6.0 gets it wrong slightly different:
both:
if [ ! "a" = "b" -a ! "c" = "d" ];then echo true;fi
and 
if [ ! "a" = "b" -a ! "c" = "c" ];then echo true;fi
dont evaluate to true.

defconfiged, compiled on Fedora 7 and running in a chrooted environment
using F7's current glibc.

Greetings,
Konrad
