[BusyBox] busybox ash bug

[Peter Willis]

a while back i found a bug in the ash shell. it is triggered by pressing
Ctrl+Left Arrow or Ctrl+Right Arrow at any point in the command line. it
will cause a segmentation fault and the shell will immediately die. i have
found this bug in the uClibc 0.9.16 root_fs releases all the way to the
current uClibc 0.9.24 root_fs releases (which uses busybox v1.00-pre4).

if anyone (vodz?) wants to take a look at ash and try to figger out what's
causing this bug i'd appreciate it, or if anyone wants to give me some hints
as to where to look for this bug in the source that'd be cool too.

The faults that bite, the jobs that thrash!
Beware the broken pipe, and shun
The frumious system crash!"
