We already had this discussion, and there was a conclusion.  We
decided to use '..' as the quoting style in plain-text documents.
I've been using it everywhere since then.  The main arguments were:

  . the ` character looks ugly on many modern displays
  . the Unicode quotes are not universally supported on text-mode terminals
  . therefore '..' has the least problems

This discussion was a kind-of tangent of the dispute triggered by the
changes in how we display `foo' quoted symbols in doc strings and
echo-area messages.

If we want '..' to be highlighted in some contexts, let's change
font-lock to support that.

And please remember that we are not talking only about comments, nor
only about ELisp files.  We are talking about all kinds of plain-text
documentation: comments, Git commit log messages, NEWS, PROBLEMS, text
files in admin/notes/, etc.
