Comment(by jstolarek):

 The patch adds --show-options option that displays all available options
 longer than two characters. Now it will be possible to use bash auto
 completion feature with GHC.

 Please ignore the second patch - I forgot to mark the checkbox to
 overwrite the existing file when uploading the new version of my patch.
