haddock generation broken

[cdepillabout]

Haddock generation appears broken for spago.

When trying to generate haddocks, I get errors like the following:

src/Spago/FetchPackage.hs:111:5: error:
    parse error on input ‘-- * if a Package is in the global cache, copy it to the local cache’
    |
111 |     -- * if a Package is in the global cache, copy it to the local cache
    |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I believe this is caused by an unfortunate feature of haddock that doesn't allow haddock-style markup in comments that are not proper haddocks.

I recently fixed something in purescript similar: purescript/purescript#3745

@cdepillabout right, I think I never generated Haddocks for the package ever. Want to have a go at this?

@f-f I'll take a look at this and see if I can get something working.

edit: Sent a PR fixing this in #516.
