[Debian-haskell] Package name in Haskell Utils

Hello,

I noticed that haskell-utils looks in two places to get the package name. update-haskell-control uses the cabal package name and scripts/10/rules uses the information from changelog. I like the idea of querying the cabal name, but I think they should both get it from just one place, to avoid:

dpkg-source -b Cabal-1.4.0.2 dpkg-source: error: source package has two conflicting values - haskell-cabal and haskell-cabal-1.4 dpkg-buildpackage: failure: dpkg-source -b Cabal-1.4.0.2 gave error exit status 255

I know this case is not standard and in cases like this I could edit the generated debian/control file, but still I don't see any reason for getting the package name from two different places.

What do you think about it?

Greetings.
