Should we occasionally merge haddock master into ghc-head?

[Edward Z. Yang]

Hello Mateusz and all,

With ghc-head and master being developed concurrently, I am wondering if
GHC developers should be allowed to occasionally merge in changes from
master.  Seems like a good service which would help Mateusz out a bit
when it comes time to update master for the next version GHC.  Or is
there some reason we shouldn't do this?

Cheers,
Edward
