Do we import patches for small fixes?

[Iustin Pop <iustin@debian.org>]

I'm looking at test-framework-quickcheck2 which has issues with
QuickCheck 2.8 and GHC 7.10. Upstream accepted a pull request long time
ago
(https://github.com/haskell/test-framework/commit/bb009e005c8a3d481c0773a038392adc4b442773)
but didn't do a release for it.

Until they do, do we use patches for this kind of issues, or do we
prefer only 'pristine' libraries?

thanks,
iustin
