   | 9621    | Move the AUTOCLEAN code into dblink.treewalk since it's      |
   | zmedico | already partially supported there anyway (for replacement of |
   |         | identical cpv). This has the benefit of guaranteeing that    |
   |         | the order of installation and removal phases is always the   |
   |         | same.                                                        |

   | 9623    | Bug #211365 - Use catpkgsplit() instead of pkgsplit() for a  |
   | zmedico | cpv.                                                         |

   | 9625    | Bug #211365 - Use catpkgsplit() instead of pkgsplit() for a  |
   | zmedico | cpv.                                                         |

   | 9628    | Make doins clean up it's own temp files. This solves an odd  |
   | zmedico | issue in dyn_package() when portage 2.1.x is installing      |
   |         | portage-2.2 and temp python module files from doins are      |
   |         | imported instead of the expected ones.                       |

   | 9630    | Fix display code that can triger a 'Invalid category'        |
   | zmedico | exception when it is given a blocker. It's only supposed to  |
   |         | execute for normal packages.                                 |

   | 9632    | Fix typos. Thanks to Arfrever Frehtes Taifersar Arahesis     |
   | zmedico | <Arfrever.FTA@GMail.Com>.                                    |

   | 9634    | * Fix broken return value for doins. * Make newins cleanup   |
   | zmedico | temp files after itself.                                     |

   | 9636    | Make sure the all resume lists are deleted when a stale one  |
   | zmedico | is encountered.                                              |

   | 9637    | When dblink.treewalk() queries for other packages in the     |
   | zmedico | same slot, filter out old-style virtual matches since they   |
   |         | are not desired.                                             |
