I ran into this issue today and came across this post while googling for an
alternative. I ended up writing this function, which seems to work pretty well
when *print-newline* is left as true.
```
;; printing goes to browser console
(let [c js/console
log (.-log c)]
(set-print-fn!
(fn [& args]
(let [args (if (= (last args) "\n") (butlast args) args)]
(.apply log c (into-array args))))))
```
