Add extra completion functionality to readline package
I propose adding a few functions having to do with readline word completion:
The rl_completion_word_break_hook variable lets us control what characters readline considers as word boundaries during completion. This function was added in readline version 5.0; we should not include this hook when compiling against earlier versions of the library.
Additionally, we should allow get/set of the rl_attempted_completion_over variable. If this variable is nonzero, readline won't use its default completer when our custom completer returns no results.
These will be used to fix ghc bug #998 (closed).
