Smartypants isn’t too smart about quotes

[iclanzan]

In words like don't and 'cause the straight quote should be converted to an apostrophe (right single curly quote).

Right now in a sentence like I won't do it 'cause I don't want to. the first ' gets converted to a left single quote, the second one to a right single quote and the third is unchanged which is wrong.

Update: Since #178, that sample sentence now translates to I won’t do it ‘cause I don’t want to. So it's correct in the middle of a word, but incorrect in 'cause.

Relatedly, I came here to report that [JavaScript](https://en.wikipedia.org/wiki/JavaScript)'s formats into <a href="https://en.wikipedia.org/wiki/JavaScript">JavaScript</a>‘s which is also the wrong apostrophe. I'm not quite sure why, given the current regex... is it being treated as at the beginning of line in this case?

I see this in a lot of editors and renderers...even MS Word and Apple Pages I have to open the glyph selector to do that. Only online editor I've seen get it right is Medium.

Closing as stale and merged.
