Well, i am not sure that all of these 109 packages are listed, or at
least i have encountered times when less than the claimed packages where
listed. I understand that the number of packages got include the other
packages of the same source package, but even so, it seems confusing and
may not always be so.

Also, i understand they are various reasons for a package not entering
testing once it is a valid candidate :

  1) because a dependecy is not a valid candidate, and has no instance
  in testing.

  2) because a dependency would break a package of testing and thus
  cannot be uploaded.

I don't think there are other reason, but maybe the update_output could
be made a bit more verbose in these cases :

  1) list all packages in this case as uninstallable.
  2) maybe list both the package that is trying to enter testing and
  (between parentheses or something) the packages that they would break.
