Without double-backticks, Sphinx wrongly turns "--version" into
"–version" with a Unicode EN DASH (U+2013), that is visually easy to
confuse with a single ASCII dash.

This certainly seems worth addressing.  But I would *really* rather find
a way to tell Sphinx not to do that rather than making all of these
tweaks - which we will certainly find ourselves having to do over and
over again.  I can try to look into that in a bit, but if somebody were
to beat me to it ... :)  

This seems to do the trick:

diff --git a/Documentation/conf.py b/Documentation/conf.py
index 3c7bdf4cd31f..8f2a7ae95184 100644
--- a/Documentation/conf.py
+++ b/Documentation/conf.py

 kerneldoc_bin = '../scripts/kernel-doc'
 kerneldoc_srctree = '..'

+# Render -- as two dashes
+smartquotes = False  

I think what Jon was looking for was the ability to selectively turn
smartquotes off for a section and then reenable it?

No that's not what I was thinking, actually.  Unless somebody can come up
with a good reason to the contrary, just disabling that behavior globally
strikes me as the right thing to do.

Well, sometimes -- when the time is right -- I like to use en-dashes.
It's probably no great loss, though.

grep finds me these interesting examples:

Not trying to be contrary, but I would prefer to keep .rst files as much
ASCII as possible.
