[BusyBox] Another bug (?)

[Per Wigren]

When using lash or hush as shell, "help" doesn't list all available applets, 
just a few of them.

HUSH:
Built-in commands:
-------------------
bg      Resume a job in the background
break   Exit for, while or until loop
cd      Change working directory
continue        Continue for, while or until loop
env     Print all environment variables
eval    Construct and run shell command
exec    Exec command, replacing this shell with the exec'd process
exit    Exit from shell()
export  Set environment variable
fg      Bring job into the foreground
jobs    Lists the active jobs
pwd     Print current directory
read    Input environment variable
return  Return from a function
set     Set/unset shell local variables
shift   Shift positional parameters
trap    Trap signals
ulimit  Controls resource limits
umask   Sets file creation mask
unset   Unset environment variable
.       Source-in and run commands in a file
help    List shell built-in commands

LASH:
Built-in commands:
-------------------
bg      Resume a job in the background
cd      Change working directory
exec    Exec command, replacing this shell with the exec'd process
exit    Exit from shell()
fg      Bring job into the foreground
jobs    Lists the active jobs
export  Set environment variable
unset   Unset environment variable
read    Input environment variable
.       Source-in and run commands in a file
pwd     Print current directory
help    List shell built-in commands


It would be nice though if ash and msh could list such nice descriptions in 
"help"...
