title: Does GHC-mod have to use full names for types?
body: <p>I'm trying to use the <code>ghc-mod</code> vim plugin to do type/syntax checking etc. However, I found that <code>ghc-mod</code> always uses full paths of types in the error messages, for example:</p>
  
  <pre><code>test.hs|71 col 13 error| Couldn't match type ‘Data.Text.Internal.Text’                                                                                   
  ||                with ‘[GHC.Types.Char]’
  || Expected type: containers-0.5.6.2:Data.Map.Base.Map

  <p>which clutters the screen and it's very hard for me to find out where went wrong. As comparison, this is the error message for the same file using <code>ghci</code>:</p>
  
  <pre><code>test.hs:71:13:
      Couldn't match type ‘T.Text’ with ‘[Char]’
      Expected type: M.Map [Char] ([(Integer, Integer)], S.Set Integer)
        Actual type: M.Map T.Text ([(Integer, Integer)], S.Set Integer)
      In the second argument of ‘M.map’, namely ‘zippedMap’
      In the second argument of ‘($)’, namely
        ‘M.map
  ...
  </code></pre>
  
  <p>which is much cleaner. Is there a way to make <code>ghc-mod</code> use short names for the types?</p>
