Not quite true: for an executable, on Windows, docs currently go by default
into $prefix\Haskell\$pkgid. See:
For a library, data files go in C:\Program Files\Common Files\$pkgid.
There's a very good reason for this: a library cannot discover its
installation location like an executable can, because it could be linked in
to an executable anywhere on the system. Hence if a library needs access
to auxiliary data files, they better be in a fixed place in the filesystem.
A library with data files cannot be fully relocatable at install-time.
However, we do need to change where docs go (they don't have to go in
$datadir, and they can be relocated at install-time).
