Oh dear, I do have a habit of overusing em-dashes. I've no problem in
theory with exchanging them for an ASCII approximation.
I suppose there's a reason it's the one dash to rule them all: :-)

As Marco pointed out, having multiple HYPHEN-MINUS symbols in a row is
probably a better replacement, as it does distinguish the em-dash from
smaller dashes better.
However, I need three for sphinx to output an em-dash here (2 hyphens
only gives me an en-dash).

So, if we want to get rid of the UTF-8 em-dash, my preferences would
be (in descending order):
1. Three hyphens: '---' (sphinx generates an em-dash)
2. Two hyphens: '--' (worst case, an en-dash surrounded by spaces --
as sphinx generates for me -- is still readable, and it's still
readable as an em-dash in plain text)
3. One hyphen as in this patch (which I don't like as much, but will
no doubt learn to live with)

But it looks like you've got several similar comments on other patches
in this series, so I'm happy for you to use whatever ends up being
agreed upon generally.

Cheers,
