Show line containing matching bracket in minibuffer

[arthuredelstein]

From Lee Spector

Some Lisp editors I've used have used the minibuffer -- now so wonderfully used in clooj for arglist-on-space (hooray!) -- for something different after typing ")" -- they show the line containing the matching "(". This is particularly nice when closing the brackets on a long function definition, when the matching brackets are scrolled off the top of the screen. In Clojure, of course, it would also be nice to do this for {} and [] brackets.

This is obviously a minor thing, but I was typing a long definition today and it was hard to balance things, so I thought I'd mention it.
