   Merged from trunk 7571:7583

   | 7572      | Make sure that portage always has all of it's RDEPENDs     |
   | zmedico   | installed first.                                           |

   | 7574      | Use == for comparison of portage_node since                |
   | zmedico   | digraph.clone() makes a deepcopy of the nodes.             |

   | 7576      | For bug #187806, use mkstemp to create                     |
   | zmedico   | tmpservertimestampfile (instead of using PORTAGE_TMPDIR).  |

   | 7578      | Fix from ferringb                                          |
   | WarnerBro |                                                            |

   | 7579      | Merge rewrite by Alon Bar-Lev from bug #130039: - Verify   |
   | zmedico   | gpg signature of snapshot if FEATURES="webrsync-gpg" is    |
   |           | enabled. - Add a --revert=yyyymmdd option that alows a     |
   |           | specific snapshot to be used.                              |

   | 7580      | For bug #187795, remove pointless digest.disjointed and    |
   | zmedico   | digest.notadded warnings since they are always added to    |
   |           | cvs automatically anyway.                                  |

   | 7582      | Document FEATURES=webrsync-gpg. Thanks to Arfrever Frehtes |
   | zmedico   | Taifersar Arahesis in bug #130039.                         |

   | 7583      | Update emerge --help and --info docs. Thanks to Arfrever   |
   | zmedico   | Frehtes Taifersar Arahesis in bug #137483.                 |
