Hi to all,
what busybox does with this option looks a little puzzling to me
and not coherent to what is written in the option's help text in all
of the 3 cases shown above:

 >>
 >>     $ ./busybox
 >>     busybox: applet not found

The help text and applet list should not be shown and no error thrown
as this is the expected behavior so it should be:

 >>     $ ./busybox
 >>     $ echo $?
 >>     0

In this other 2 cases the error messages are completely
broken and non-sense as they misrepresent the long name option
which is not correctly parsed as the applet name

 >>     $ ./busybox --help
 >>     -help: applet not found
 >>
 >>     $ ./busybox --list
 >>     -list: applet not found

The expected behavior should be something like this

 >>     $ ./busybox --list
 >>     --list: unknown option
 >>     $ echo $?
 >>     1

or following what was the busybox standard until now
print the usage text of the applet (or busybox), but
as we have none to print.....

So it seems to me that this patch could be improved.

Ciao,
Tito
