Comment (by judahj):

 One more note: this patch requires readline version 5.0 or later.  In
 contrast, the proposed changes in #1141 are compatible with earlier
 version of readline (they will only include the relevant functions if
 compiled against a new enough version of the library).

 Thus, there probably needs to be something changed or added in the
 configuration scripts of ghc itself to bump up the requirements for
 readline.
