the busybox menuconfig triggered my "inacceptable number of spelling mistakes"
upper level, so I decided to make a patch ;-)

I also improved some wording to describe some things in a better way.

Many thanks for an incredible piece of software!

Tha 'ash' shell adds about 60k in the default configuration and is
the most complete and most pedantically correct shell included with
busybox. This shell is actually a derivative of the Debian 'dash'
shell (by Herbert Xu), which was created by porting the 'ash' shell
(written by Kenneth Almquist) from NetBSD.

Compile ash for reduced size at price of speed.
config CONFIG_HUSH
bool "hush"
default n
help
hush is a very small shell (just 18k) and it has fairly complete
Bourne shell grammar. It even handles all the normal flow control
options such as if/then/elif/else/fi, for/in/do/done, while loops,
etc.
It does not handle case/esac, select, function, here documents ( <<
word ), arithmetic expansion, aliases, brace expansion, tilde
expansion, &> and >& redirection of stdout+stderr, etc.
config CONFIG_LASH
bool "lash"
default n
help
lash is the very smallest shell (adds just 10k) and it is quite
usable as a command prompt, but it is not suitable for any but the
most trivial scripting (such as an initrd that calls insmod a few
times) since it does not understand any Bourne shell grammar. It
does handle pipes, redirects, and job control though. Adding in
command editing makes it a very nice lightweight command prompt.
config CONFIG_MSH
bool "msh"
default n
help
The minix shell (adds just 30k) is quite complete and handles things
like for/do/done, case/esac and all the things you expect a Bourne
shell to do. It is not always pedantically correct about Bourne
shell grammar (try running the shell testscript "tests/sh.testcases"
on it and compare vs bash) but for most things it works quite well.
It also uses only vfork, so it can be used on uClinux systems.
