Which seems to work pretty well so far. I recommend people try it.

$ source bash-completion/cabal
$ cabal <TAB><TAB>

Next step is adding a fast cabal list --simple-output so we can complete
on package names as well as commands and flags.

This is not something that we can easily get Cabal to install for us I
think since different systems put their bash completion code in
different places, but distro packages can and should install it
according to their distro policy.
