thinking about this line some more, how about this:

 * haddock remains unmodified.
 * The package scripts in haskell-devscripts and ghc6 do not _copy_
the .txt file to /usr/lib/ghc-doc/hoogle/, but create a symlink.
 * the hoogle trigger acts on /usr/lib/ghc-doc/hoogle and calls hoogle
convert on these files. But, as they are symlinks, the trigger knows
their original location in /usr/share/doc/*/html, so it knows the
correct path. This is passed to hoogle convert (which we need to patch),
yielding the same effect as a @url line, without modifying any files.

We need to ensure that the .txt files are not compressed, but we can
easily do that by passing -Xtxt to dh_compress.

What do you think?
