   Merged from trunk 9383:9385

   | 9384    | Bug #211365 - Use catpkgsplit() instead of pkgsplit() on the |
   | zmedico | cpv in the dblink constructor since otherwise weird          |
   |         | categories containing numbers can make pkgsplit() return     |
   |         | None (likely related to version regex handling).             |
   |         | (branches/2.1.2 r9383)                                       |

   | 9385    | For depclean/prune unmerge order, if there are no            |
   | zmedico | dependencies between package then just unmerge them          |
   |         | alphabetically.                                              |
