The only note in the file was about the lack of documentation due to
DFSG issues, but upstream has kindly solved this problem by
dual-licensing the docs.

- d/control:
  + B-D on dh-elpa.
  + Add new elpa-poke binary package.
- d/elpa-poke.elpa: Install Emacs Lisp files.
- d/poke-pkg.el.in: New -pkg.el file needed for dh-elpa.
- d/rules:
  + Generate d/poke-pkg.el from the .in file, replacing the upstream
    version.
  + Run dh_elpa.

We are dropping patches 0002, 0003 and 0004 because they are not
needed anymore.  We are adjusting patch 0001 to only remove the
documentation from jitter, because poke's documentation is now
included in the DFSG tarball.

Update to upstream version '1.1+dfsg'
with Debian dir 67d9f2433486b2f86904f12e3e8389567c63d3f3

Upstream has relicensed the documentation using GPL-3+, which is
DFSG-compatible.  This means that we can re-add the doc/ directory.

Fix build on 32-bit architectures.
