   | 9160    | Bug #162542 - When dropping privileges for                   |
   | zmedico | FEATURES=userpriv, automatically detect permission problems  |
   |         | with CCACHE_DIR and recursively adjust permissions only when |
   |         | necessary.                                                   |

   | 9162    | Bug#204668 - Fix WORKDIR quoting in econf() when updating    |
   | zmedico | config.guess and config.sub.                                 |

   | 9163    | Bug #204425 - Remove --delete-after from the default         |
   | zmedico | PORTAGE_RSYNC_OPTS. This allows the rsync program to choose  |
   |         | the preferred --delete algorithm, or the user can choose one |
   |         | via PORTAGE_RSYNC_EXTRA_OPTS.                                |

   | 9164    | Make sure that portdb.findname() returns the correct ebuild. |
   | zmedico |                                                              |

   | 9165    | Fix the "Appending to PORTDIR_OVERLAY..." feature which was  |
   | zmedico | broken by the previous commit.                               |

   | 9166    | Bug #203316 - Fix isvalidatom() to properly detect invalid   |
   | zmedico | operators used together with slot atoms. Thanks to Arfrever  |
   |         | Frehtes Taifersar Arahesis <Arfrever.FTA@GMail.Com> for the  |
   |         | patch.                                                       |

   | 9167    | Bug #203887 - Implement RESTRICT=installsources for binaries |
   | zmedico | that are not compatible with debugedit.                      |

   | 9176    | Bug #162450 - Try to avoid having so many bugs marked        |
   | zmedico | UPSTREAM by encouraging users to report 'poor programming    |
   |         | practices' QA issues upstream and show them the $HOMEPAGE    |
   |         | for convenience.                                             |

   | 9177    | Add a DESCRIPTION.toolong warning for when the DESCRIPTION   |
   | zmedico | line is over 80 characters long. Thanks to Betelgeuse for    |
   |         | the patch.                                                   |

   | 9178    | * Make pkgcmp() pass the ebuild revision directly into       |
   | zmedico | vercmp() since there is code there to handle it already.     |
   |         | This eliminates some redundant revision comparison code.     |
   |         | Thanks to peper for the patch. * Add some vercmp() test      |
   |         | cases for comparison of ebuild revisions.                    |

   | 9179    | Add a new "ebuild.autotools" check for when ebuilds call     |
   | zmedico | autotools directly instead of using autotools.eclass. Thanks |
   |         | to Betelgeuse for the initial patch.                         |
