Okay, so how about we:

  1) Turn off sftp access.
  2) Apply the diff at the end of this mail :-).
  3) Update the developer instructions accordingly.

Thanks.  (After we agree on the course of action, I'll have some changes
to submit to administration/bzr.txt too.)

Regarding commit emails: let's just continue using bzr-hookless-email
for now.  It works, and right now the problem we're trying to solve is
bzr+ssh:// access.  We can tackle other Bazaar issues afterwards.

Below is the diff; please review.  If you like it, my next step will be
to come up with the developer instructions so those currently using
sftp:// can switch over.  (Naturally, we'll warn them first and set a
flag date.)

Restore Bazaar bzr+ssh:// access, but this time without plugins.

* /usr/local/bin/sv_membersh: Suppress logging in the modern way.
  Add the '--no-plugins' option to the bzr serve command.

* /etc/ Set use_bzr to 1.
