wrong-section-according-to-package-name, libdevel => haskell

[trentbuck@gmail.com (Trent W. Buck)]

Using cabal-debian, I get:

W: libghc6-highlighting-kate-dev:
   wrong-section-according-to-package-name
   libghc6-highlighting-kate-dev => haskell

W: libghc6-highlighting-kate-prof:
   wrong-section-according-to-package-name
   libghc6-highlighting-kate-prof => haskell

This is because "haskell" section was recently added.  I expect this is
a trivial patch to cabal-debian, but shave any more yaks today I'll
forget what my final goal is.
