Currently the docs do just use --datadir= and --datasubdir= .

I think it'd be perfectly reasonable to follow the lead of autoconf here
and have slightly finer grained control with respect to the kinds of
files we're installing. Autoconf distinguishes docs (and various kinds
of docs, html, ps, pdf, man etc) from the generic datadir.

So yes, if you want to extend cabal in this direction I'm happy to
review patches.
