Change Command Line Output to Node Version with Attribute 2

[jackrieger]

Is there a way to change the command line tool to have the behavior from the node version with attribute 2:

"2" Same as smarty_pants="1", except that it uses the old-school typewriter shorthand for dashes: -- (dash dash) for en-dashes, --- (dash dash dash) for em-dashes.

I think this allows greater flexibility.
