smartypants: Normalize dash replacement

Browse source 
The original SmartyPants comes with three dash replacement modes:

	1 =>  "--" for em-dashes; no en-dash support
	2 =>  "---" for em-dashes; "--" for en-dashes
	3 =>  "--" for em-dashes; "---" for en-dashes

Sundown now runs with number 2, because I am opinionated and I think
that the other 2 options are stupid.
