 * Drebs wrote a patch to add '--list-packets' functionality to python-gnupg,
   and I would like to include it without deleting its history. This is a
   rather strange merge, however, because not only does it merge an entirely
   different repo, but also an entirely different repo of an entirely different
   project, Soledad.
 * The file we wanted was src/leap/soledad/util.py, and the commands taken to
   complete this merge were as follows:

   git clone git@github.com:isislovecruft/soledad.git soledad-copy
   cd soledad-copy
   git remote rm origin
   ## Remove the files and any history which mentions those files which are
   ## not in the src/leap/soledad directory:
   git filter-branch --subdirectory-filter src/leap/soledad -- --all
   ## Then do the same for every file and subdirectory which is not util.py:
   git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch \
       src/leap/soledad/__init__.py' HEAD
   git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch \
       src/leap/soledad/server.py' HEAD
   git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch \
       src/leap/soledad/shared_db' HEAD
   git filter-branch -f --index-filter 'git rm -r --cached --ignore-unmatch \
       src/leap/soledad/tests' HEAD
   git filter-branch -f --index-filter 'git rm -r --cached --ignore-unmatch \
       src/leap/soledad/backends' HEAD
   cd ..
   git clone git@github.com:isislovecruft/python-gnupg.git python-gnupg-copy
   cd python-gnupg-copy
   git remote add soledad ../soledad-copy
   git fetch soledad
