Subject: [PATCH]    Merged from trunk 8226:8243

   | 8233    | In depgraph.create(), if a direct circular dependency is not |
   | zmedico | an unsatisfied buildtime dependency then drop it here since  |
   |         | otherwise it can skew the merge order calculation in an      |
   |         | unwanted way.                                                |

   | 8235    | Fix broken imports.                                          |
   | zmedico |                                                              |

   | 8236    | Bug #196652 - Check for useless ABOUT-NLS|COPYING|LICENSE    |
   | zmedico | files in dodoc arguments.                                    |

   | 8238    | Remove a redundant self.treeVirtuals deepcopy from the       |
   | zmedico | config constructor.                                          |

   | 8240    | Fix config.setinst() to return early when the given package  |
   | zmedico | already provides the virtual.                                |

   | 8242    | Fix the version Id tag.                                      |
   | zmedico |                                                              |

   | 8243    | Print the Id tag an it's own line to avoid going over 80     |
   | zmedico | columns.                                                     |
