completely mechanical changes or a single contributor contributing less 
than 15 lines of changes total is generally not significant for 
copyright.[1]  The Haddock is more likely to be significant and you 
should probably find its author(s) too.  ..although there's not very 
much readline docs (besides type-signatures) on 
http://www.haskell.org/ghc/docs/latest/html/libraries/index.html
