  * Separate the construction of the exclusion list from its use
  Previously directly inserted packages into the excluded package
  list. Now we generate a list of them and then add them. We want
  the list of newly excluded packages separately because it is
  interesting information to report to the user when -v is on.

    M ./Distribution/Client/Dependency/TopDown/Constraints.hs -15 +17
