setup.exe handles same packages in multiple mirrors badly

Sure, a feature like this could be added to setup*.exe.  No doubt
anyone that wants to offer a patch to support this would receive a
thoughtful review of it. :-)

A few thoughts and points of clarification.

   1. cygwinports, while a commonly referred to site on this list, is not a
      site supported by cygwin.com or this list.

   2. cygwinports is more akin to a repository than a mirror.  All Cygwin
      (current, up-to-date, and valid) mirrors contain the same packages.
      cygwinports contains, typically, packages that are not distributed
      by cygwin.com and vice-versa.

   3. setup*.exe currently has a design to support Cygwin mirrors.  It's
      currently flexible (or dumb? ;-) ) enough to consider other
      repositories as well but this is not its primary function and doing
      so may reveal some of its limitations (as you've found).
