For the record, abstract-deque was neither one of the packages fixed
previously, nor does its .cabal file even contain a test section at
all, much less one with a conditional.  So if cabal-install-0.10 is
failing to read it, it is because of some different problem.  But I
agree with Bryan in principle that we need a more principled approach.
