Summary:                    sed and grep don't work inside backticks is
static-busybox
Description: 
I've also posted this bug here:
http://bugs.gentoo.org/show_bug.cgi?id=157118

Short copy-paste:

busybox sh
TEST="`echo abc | sed -n '/abc/p'`"; echo $TEST
# gives abc, as expected

busybox.static sh
TEST="`echo abc | sed -n '/abc/p'`"; echo $TEST
# gives empty line!!!!!!!

This bug hit me when trying to make an initramfs (hence the need for the
static
binary); it took me 3 hours to pin it down to the usage of sed INSIDE
backticks
(or the $() construct).

This also fails: echo `echo abc | grep abc`
this works: echo `echo abc | awk '/abc/p'`

I tried this bug on 3 different machines and was able to reproduce it on
version 1.2.2.1; this bug does not exist on 1.1.0 and 1.2.1
