[Haskell-cafe] Human-friendly compiler errors for GHC

> Personally, I would suggest make it take up less space. A newline for each match may be alright if there are only 3 suggestions, but past that it begins to take up too much of the screen. Columns are nice, or perhaps a limit on how many matches will be displayed (with more available if the user asks?).

I've actually limited it to 3 matches displayed in the current
implementation, but indeed it would probably be good to display the
matches in columns instead.
