Title: allow "-" hyphen as an option argument

An argument which has only one character of "-" hyphen have been not accepted.

ex. node test -a - --bravo - --charlie=- - -- -

STDIN and STDOUT are often named as "-" in most UNIX commands.
This patch will allow to use "-" hyphen arguments.
Test script is included as well.
