I regularly use --- for em-dashes and -- for en-dashes.  Markdown will
automatically translate 3 ASCII hypens to em-dashes, and 2 ASCII
hyphens to en-dashes.  It's much, much easier for me to type 2 or 3
hypens into my text editor of choice than trying to enter the UTF-8
characters.  If we can make sphinx do this translation, maybe that's
the best way of dealing with these two characters?
