Bug#405108: busybox: should have a --list option to list all supported commands

[Russell Coker <russell@coker.com.au>]

Package: busybox
Version: 1:1.1.3-3
Severity: normal


busybox | tail -19 | tr , \\\\n | sed -e "s/ \|\t//"|grep .|grep -v busybox

Currently to get a list of the supported commands in busybox I need to use
the above shell code.  This is ugly and will cause problems if the number of
lines required changes.

What we need is a --list command-line option that will display all supported
options one per line to stdout without any additional commentary.

See bug #338405 for one example of what I want to do with this.
