Summary:                    tr mishandles case where first pattern set starts
with hyphen
Description: 
GNU Coreutils tr:
    "echo foo-bar | tr - _" yields "foo_bar"

Busybox tr:
    "echo foo-bar | tr - _" yields "foo-bar"

This occurs in all versions of Busybox at least as far back as Busybox
1.00.

The tr applet does not support "--" for option/argument disambiguation
(eg. "tr -- - _"), so coding around this behaviour is awkward (have to use
something like "tr '\055' _").
