I do think we should put something in to guide people in the right
direction.  And yes, it should, itself, be light-handed and minimal.

I do, however, also believe that it should apply to relatively recent
docs-next :)

I think this is about where I figured out why I'm not 100% ready to jump on
this.  What we're doing here is mixing two things: information on how to
write documents, and information on how to convert existing documents.

I'm not really opposed to applying the patch as-is, but I do wonder if what
we really need is a new section aimed specifically at people doing
conversions?  The concerns *are* a bit different, and there's more
information we could put into a conversion section that isn't relevant to
others.  Plus we could remove it some day far in the future when
everything's converted :)

I think we should add a sentence somewhere saying:

  Note that, if the sentence before the block ends with ":", you can simply
  add a second colon rather than putting in a separate "::" line.

I've had to tell a few people that.  It's a tiny detail, but one that does
improve the readability of the resulting documents and reduce the
intrusiveness of conversions.

Thanks,
