haddockPref determines where the documentation is built; mkHaddockDir
says where it is installed, currently $datadir/$datasubdir/doc/html/$pkg,
where $datasubdir defaults to $pkgid.  That default doesn't seem right
in any case.  Perhaps we want

 --docdir (defaulting to $prefix/share/doc on Unix and something else
   on Windows)

 --htmlsubdir (defaulting to $pkgid/html)
