[Haskell-cafe] Cabal exit codes when work to be done

[Andrew Cowie]

Is there a way to run e.g. `cabal install --only-dependencies` and have
it return a non-zero exit code if, for instance, there IS something to
do?

I tried `--dry-run` but the exit code is still 0 if something is
missing.

[or have it return non-zero if there isn't work to do, or...]
