 * [#1707](https://github.com/clojure-emacs/cider/issues/1707): Allow to customize line truncating in CIDER's special buffers.
 * [#1876](https://github.com/clojure-emacs/cider/issues/1876): Set pretty-printing width with `cider-repl-pretty-print-width`. If this variable is not set, fall back to `fill-column`.
