   | 11446   | Fix typo in "directory" spelling. Thanks to Ofer Wald in bug |
   | zmedico | #219957.                                                     |

   | 11449   | For consistency, show [0] in the repo display instead of     |
   | zmedico | suppressing it. Now the repo display and [0] will only be    |
   |         | suppressed when [0] is all that would show for every         |
   |         | package. Thanks to Joe Peterson <lavajoe@g.o> for the        |
   |         | suggestion.                                                  |

   | 11450   | Use shlex.split() to split CONFIG_PROTECT and                |
   | zmedico | CONFIG_PROTECT_MASK.                                         |

   | 11451   | Update ROOT docs wrt make.conf since it can now be set there |
   | zmedico | regardless of PORTAGE_CONFIGROOT setting.                    |

   | 11452   | Fix isprotected() call in dblink._collision_protect() to     |
   | zmedico | properly account for $ROOT.                                  |

   | 11453   | Add a new is_protected command which queries whether or not  |
   | zmedico | CONFIG_PROTECT applies to a given file, using logic          |
   |         | identical to the merge code.                                 |

   | 11454   | Add a new src_prepare phase function which is called         |
   | zmedico | in-between src_unpack and src_configure (and bump EAPI to    |
   |         | 2_pre3). Thanks to Ciaran McCreesh for the suggestion.       |
