Comment (by kolmodin):

 With the patch 624a7c5a2eee0c0ba486a45550680052c2c79849 mentioned above,
 the bulk of the work is done.

 What remains is to;

   - Clean up DynFlags, a lot of the lines are over 80 chars
   - Let more people look at the partitioning of the flags into
 ghc/ghci/all, correcting any mistakes where a flag has been assigned to
 the wrong mode
   - Some flags are defined in DynFlags but not documented in the User's
 Guide. Should they be marked as hidden? Mail ghc-devs and find out.
   - Possibly update documentation about ghc's new ability to use
 --interactive and --show-options together.
