[BUG] 'find' does not support '--'

[Martijn Dekker]

Busybox 'find' does not support '--' to signal end of options, as POSIX 
requires[*]. (This is the standard way of allowing arguments, in this 
case path names, starting with a dash.)

$ ./usr/bin/find -- /dev/null -print
find: unrecognized: --
[long usage message omitted]

Thanks,

- M.
