Addendum to voting procedure

[Guy.Steele at CMU-10A]

I forgot to provide a way to indicate "no vote" on a question.
Use "-" for this purpose.  So a response might look like:

~ xabyb n-xxb arn-- --ax- xxa-- -x-

Second, I want to emphasize again that this ballot, as with all
previous ballots, is not necessarily a majority-rules vote,
but an attempt to determine for each question whether there is
a general consensus or not.  If there is consensus, I take that
as a mandate to edit the document accordingly; if not, the
question remains open for discussion.
