[BusyBox] awk bug in busybox 1.00-rc2

[Henry Pan]

awk in busybox 1.00-rc2 does not accept "\n"

for example
# echo 1 2 | awk '{print $1"\n"$2}'
1
2
# echo 1 2 | busybox awk '{print $1"\n"$2}'
awk: cmd. line:1: Unexpected end of string

I confirm this problem only exist in busybox 1.00-rc2, but not in older version
