hadrian: docs-haddock target is a big hammer, make it more fine-grained
If I am working on the haddock documentation for a particular package then I just want to rebuild haddocks for that package.
It would be convenient if docs-haddock
could take an additional filter argument to specify which package I want haddocks built for.
For example
docs-haddock:template-haskell
will just build the haddock documentation for the template-haskell library.
