Merge the potato branch:
* main/dpkg.8: don't list all authors but refer to THANKS file
* debian/control: correct Build-Dependencies for ncurses
* debian/control: update extended description to not list dependencies
  for dpkg-dev
* Update lots of documentation
* main/enquiry.c: handle failed open of /dev/tty
* main/remove.c: revert earlier patch from Oct 11 1999 to remove
  conffiles before removing directories. Due to the changed execution
  order conffiles were no longer around when the postrm was run.
  which is not what we want.
* methods/Makefile.in: create $(admindir)/methods/mnt
* scripts/dpkg-gencontrol.pl: undo Source-Version changes
* scripts/dpkg-source.pl: remove sticky bits from directory when
  unpacking source
* scripts/install-info.pl: partially apply patch from Jammin Wheeler
  <jammin@life.eu.org> to clean up errors
* scripts/update-alternatives.pl: implement --verbose
