GHC HEAD vs Hackage, panic-free edition

[Edward Kmett]

Carter and I started a conversation with the travis-ci guys about how to
support multiple Haskell versions a year and a half ago, but it fizzled out
and not much came of it.

At last check they were definitely leaning more towards supporting a few
haskell-platforms as they came out rather than something so
maintenance-heavy as tracking HEAD.
