bug#7035: Savannah Emacs page fixes

Could we find someone to maintain it up-to-date instead?

We could turn off CVS access, indeed, tho I'm not sure what are the
consequences in terms of the old CVS repository: would it still be
accessible via `cvs'?  Would it disappear completely?  Would we care?

This page is auto-generated.  So to add those lists, we'd have to
change them into standard lists managed by lists.gnu.org.  Since they're
also available as usenet groups, I'm not sure how easy such a switch
would be.

Again, this is auto-generated, and I have no idea if a switch somewhere
in the mailing-list config controls this message and if so which one,
