should haddock.ghc be a sub-repo of ghc?

The point here I think, is that we should develop against the *released*
version of the GHC API, and then update our code whenever there's a new
version. Currently, that only seems to happen once per year. So coping
with that is acceptable, IMHO.

I admit that there's a trade-off here. If changes were followed
immediately into other projects, that might lead to better, more
thought-through and immediate integration of features. But I think we
should do integration later, to avoid bottlenecks in the development of
GHC.

I would certainly *like* it if those who implement new GHC syntax would
propagate those changes into Haddock though. That way, they would also get
to decide how new syntax should be rendered in the documentation.
