Summary

0000869: msh fails to handle pipes properly

Description

if you run `ls | cd` in msh, the shell will try and execute the output of ls and then quit:
vapier@vapier 1 busybox $ ./busybox msh

BusyBox v1.2.0-pre0 (2006.05.05-18:18+0000) Built-in shell (msh)
Enter 'help' for a list of built-in commands.

# ls /dev/null | cd
# /dev/null: cannot execute
# vapier@vapier 1 busybox $

Notes
(0003994) vda 02-11-08 10:09	Actually, msh.c has code which detects and complains about these (see "#ifdef COMPIPE"), but it was disabled. I am enabling it, and tentatively explain how it can be possibly fixed. Not actually fixing for now.
