Gearing up for a 1.18 release

May I ask you to include haskell suite support in this release?
Haskell suite adds a new compiler flavor to Cabal, except it is not
tied to any particular compiler. Hopefully, this may be the last
compiler flavor added to Cabal.
It is already used by the haskell suite interface generator.
Here's the patch (on top of the cabal-install-1.18 branch):
I can also create a pull request if needed.
I realize that including new code just before the release is usually not
a good idea, but in this case it's very low-risk. It doesn't change the
public Cabal API. All it does from the user's perspective is introducing
a new switch (--haskell-suite), which shouldn't impact in any way users
who don't use it.
The only possible issue is during compilation. Speaking of which, I've
verified that Cabal and cabal-install build with this patch using GHC
7.6.3 and 7.0.4.
Cabal's policy is to support being built by versions of GHC that are up
to 3 years old. That would be 6.12.3, released 12 June 2010. Cabal with
the patch indeed builds on 6.12.3; however, cabal-install fails to

cabal: cannot configure process-184.108.40.206. It requires directory ==1.0.*
For the dependency on directory ==1.0.* there are these packages:
directory-220.127.116.11, directory-18.104.22.168, directory-22.214.171.124, directory-126.96.36.199 and
directory-188.8.131.52. However none of them are available.
