I agree that the way this has been presented is awful.

I'd ask that you reconsider.  Looking at patch 2, I prefer what is
written there.  I don't think it adds cognitive load when reading the
plain docs.  I find the "copy and paste from html" argument not very
convincing, but I do like "copy and paste from rst", which this enables.

I also have a certain fond memory of how the plan9 people set up 'rc'
(their shell) so that ";" was both an empty statement, and the default
prompt.  So you could copy-paste lines starting with the ; prompt and
they'd work.  It's a small usabillity improvement, but it is there,
and wow is it annoying when you don't have it any more.
