Early trial builds of 2012.2.0.0

[Chris Dornan]

That is it -- certain situations trigger 0.14. into providing the extra
information, but only for 0.14.0 AFAICT.

(I noticed the behaviour by switching between the old and new cabal while
running prepare.sh.)

I think the change is correct and required in general.
cabal-install-0.14.0 warns if there are reverse dependencies of reinstalled
packages, because these might be broken after the installation process. If
the set of potentially broken packages is non-empty, it implicitly adds -v,
because without it, the user won't be able to see which packages are
reinstalled. I'm sorry that this causes problems for you.

Cheers,
