commit dd56eb1efc11bcbd60ab0b77ca3e4f949d7d0844
Author: Herbert Valerio Riedel <hvr at gnu.org>

    Merge new commands from ghci-ng (re #10874)
    
    This adds the new commands `:all-types`, `:loc-at`, `:type-at`, and
    `:uses` designed for editor-integration (such as Emacs' `haskell-mode`).
    
    This was originally implemented by Chris Done on
    
      https://github.com/chrisdone/ghci-ng
    
    and has been in use by Emacs' `haskell-mode` for over a year already,
    and closely missed the GHC 7.10 release back then.
    
    I've squashed the commits, rebased to GHC HEAD, and heavily refactored and
    improved the patch.
    
    Tests will be added in a separate commit.
