So this seems generally good though - as is my usual style - if it were
mine I'd be trying to find a way to make it significantly shorter.

I could certainly bikeshed a lot of things - I'm not convinced about the
whole shallow-clone business, for example - but I'll try to restrain
myself.

I do wonder if all that back-and-forth actually makes things easier, and
it definitely impedes use of the RST file.  I recognize that you're
trying to do something a bit different here, though, and don't want to
get in the way of the experiment.  Given the purpose, though, I do have
a couple of little thoughts:

- Somewhere at the top of the RST file should be a prominent link to the
  rendered version, presumably on kernel.org.  It could perhaps be in an
  RST comment that doesn't show up in the rendered version, saying
  "perhaps you really want to read this ----> over there".

- Eventually we should probably make the link to this document more
  prominent on the front page - once we've figured out what we're doing
  there :)

Anyway, those quibbles aside, I think we should probably just apply this
after the merge window.

Thanks,
