Code review comment for lp:~al-maisan/bzr-builddeb/odd-behaviour-385667

Hello there!

This branch fixes

  - the glitch described in
    https://bugs.launchpad.net/bzr-builddeb/+bug/385667/comments/1 and
  - the problem with creating debian changelog files in empty branches

The other problems described in bug #385667 either do not occur any more
(negative upstream version numbers) or are not specific to merge-upstream
(deleted .bzrignore files).

Please take a look and let me know what you think. Thanks!
