   | 11916   | Fix new* and do* ebuild helpers to generate consistent error |
   | zmedico | messages for missing files and generate an appropriate QA    |
   |         | Notice when such an error is detected in the build log.      |
   |         | Thanks to Diego 'Flameeyes' Pettenò <flameeyes@g.o> for the |
   |         | suggestion.                                                  |

   | 11918   | Bug #216190 - Make dblink.treewalk() bail out rather than    |
   | zmedico | install a package with file paths containing newlines.       |

   | 11920   | Bug #243022 - Inside dblink.mergeme(), when merging a        |
   | zmedico | directory and a symlink is in the way, verify that if points |
   |         | to a directory before accepting it, otherwise move it out of |
   |         | the way.                                                     |

   | 11922   | Bug #236683 - Fix PermissionDenied handling to report the    |
   | zmedico | exception type.                                              |

   | 11924   | Make digestgen() handle PermissionDenied internally by       |
   | zmedico | returning failure, so callers like repoman don't need        |
   |         | exception handling.                                          |

   | 11926   | Bug #236714 - Handle PortagePackageException raised from     |
   | zmedico | Manifest.create().                                           |

   | 11928   | Bug #173284 - Do not traverse hidden directories such as     |
   | zmedico | .svn or .git when search for protected files.                |

   | 11929   | Bug #173284 - Do not traverse hidden directories such as     |
   | zmedico | .svn or .git when search for protected files.                |

   | 11931   | Remove stray print statement from previous commit.           |
   | zmedico |                                                              |

   | 11933   | Bug #173284 - Update config update counting code in          |
   | zmedico | chk_updated_cfg_files() so hidden directories are ignored.   |

   | 11935   | Bug #236207 - Replace some hardcoded colors with color       |
   | zmedico | codes, and use portage.output.EOutput() where appropriate.   |
