[slime-devel] Set *print-right-margin* depending on width of repl window (in slime-repl contrib)

hi, The attached patch sets (binds) cl:*print-right-margin*, when evaluating a form from the repl via slime-repl-eval-string, to the width of the repl window. Not a big deal, but does make describe's output much cleaner (thanks to H4ans in #lisp for the inspiration). -- -marco
