Added as proposal 178.

(As a sidenote, the specifications and proposals are  no longer part
of the tor source repository; they've got their own repository now.
You can browse them at

To check out the specification repository, run
    git clone git://git.torproject.org/torspec.git

For other information on the repository, see

This is probably a bit bikeshed, but the ability to add new parameters
in a hurry has been pretty useful in the past.  Instead of requiring a
majority of authorities, I'd suggest that we require 3, or a majority,
whichever is smaller.  (I suggest "3" because it's the smallest number
of voters on a parameter for which the median is not unilaterally
determined by a single authority.)
