Cabal hack night suggestions

Hi David,

Great to here that you're going to hack on cabal. We need all the
contributors we can get!

The general roadmap for 1.20 is here:

The "Do the right thing automatically" section is probably the most newbie

Other than that we really need to get the bug tracker under control. This
means triaging bugs and fixing those that need fixing and closing the rest.
I took a stab at this a while ago but if you want something to get your
feet wet, I suggest grabbing something that looks interesting from the bug

As for hacking on cabal, I suggest using sandboxes, like so:

cd cabal/cabal-install
# only once:
cabal sandbox init
cabal sandbox add-source ../Cabal
cabal install -j --only-dep
# to (re)build:
cabal build
