[Bug: Busybox 1.22.1] false return 0 instead of 1 with '--help' switch.

[Xabier Oneca -- xOneca]

Hello list,

I want to highlight what GNU coreutils' help docs (info coreutils
'false invocation') says about false when invoked with --help:

> Note that `false' (unlike all other programs documented herein)
exits unsuccessfully, even when invoked with `--help' or `--version'.

I think Busybox should do the same with the applet.

Cheers,
