When I place cursor after special variable containing bit-vector, slime tries to display it whole in minibuffer, which is slow and if size of vector is very large it may crash slime:

(defparameter *foo* (make-array 20000000 :element-type 'bit)) *FOO*

The following patch should fix the problem. It's also possible to have long symbols, but i think it's very uncommon.
