bashCompleter :: String -> Completer

Run a compgen completion action.

Common actions include file and directory. See http://www.gnu.org/software/bash/manual/html_node/Programmable-Completion-Builtins.html#Programmable-Completion-Builtins for a complete list.

requote :: String -> String

We need to do this so bash doesn't expand out any ~ or other chars we want to complete on, or emit an end of line error when seeking the close to the quote.
