Spaced hyphens into spaced dashes

[joshuagoodwin]

We all know that "---" and " -- " are changed into em-dashes (—), and that "--" is changed into an en-dash (—). But another bit of formatting really ought to take place - space-surrounded hyphens, like that one, ought to be turned into en-dashes by wp-includes/formatting.php. This is what Microsoft Word does, and - ​says Wikipedia - the style is adopted by many publishers. So this easy-to-implement feature really ought to be implemented - it happens with the likes of Textpattern.

Yes, yes, it's not in a .diff format. My sincere, sincere apologies for this. Changes in lines 47 & 48.
