Merge lp:~debfx/ubuntu/precise/pkgbinarymangler/dependency-cycle into lp:ubuntu/precise/pkgbinarymangler

[Felix Geyer]

  * pkgstripfiles, symlink_doc(): Don't create symlinks that would point to
    the same package. (LP: #923343)
  * test/run: Add test_doc_symlink_dependency_cycle() to make sure that
    pkgstripfiles works correctly when there is a dependency cycle inside
    a source package.

[Dave Walker (davewalker)]

pkgstripfiles change looks good and simple.. the Test looks valid.. Happy to upload if you can confirm it's ready..

Thanks.
