IRC chatting revealed at least one issue.  Built-Using can make a
"newer" source version appear in testing.

"""
build foo against bar 2.  bar 1 is in testing.  put foo in testing.
"""

The current suggestion is to use the Packages_X files to determine which
source versions to use (and ignore the rest).  Though:

"""
09:21 < adsb> does it dtrt with smooth updates and/or faux packages?
(not expecting an answer right now, just a thought)
[...]
09:22 < adsb> it = "inferring Sources from Packages"
"""

As always, test cases are welcome at [1].
