Automatically indent correctly after the user types a newline, and provide a way for the user to trigger re-indentation (according to Clojure formatting standards) of the current line or selection.

As, for example, in Gorilla REPL with shift-tab. Many other Clojure/Lisp environments provide similar functionality, and some coders/teachers (like me :-) consider this to be an essential feature.

Note that this is not a request for paredit or parinfer, which some (like me :-) consider to be problematic.
