Log Message:
Update to version 0.8.

Changes in version 0.8:

  * Haddock has a Cabal build system, and will build on Windows without
    Cygwin or MSYS.  GHC 6.4 or later is required.

  * New options: --comments-base, --comments-module, --comments-entity
    for generating links to pages (eg. wiki) for collecting user comments.

  * New options: --source-base, --source-module, --source-entity
    for generating links to source code.  Haddock now understands
    {-# LINE #-} pragmas, which means it can figure out the correct
    name for the source file even if the file is preprocessed.

  * Haddock generates output for populating the Hoogle search engine.

  * New markup <<url>> for including images.
