installing git-annex with cabal-install is quite long and requires to install
some heavy packages. It also has several external lib dependencies and needs a
few configuration flags to build so it is quite difficult to install too.
This formula should make it easy and quick to install with a bottle.

The huge number of haskell dependencies is built within the formula and statically
linked to git-annex. The haskell libraries built are discarded - cabal-install
should be used instead of this package in order to keep them.

The default behavior of `brew deps foo bar` is to return the
intersection of the deps of foo and bar. This option returns the union.

This means e.g. `ghc` can find `gcc-4.8` at runtime.

Avoid throwing unnecessary exceptions by checking for paths existing and
creating formulae as late as possible. Additionally use instance
variables for some caching.

 - the executed script is the formula file, build.rb is a library
 - ruby is invoked directly, so it wouldn't need to be executable anyway

Without it, String#undent would fail on unindented strings, e.g.:
