nth function produces different results from clojure when using a negative index on a sequence
Description
(nth (range 2) -2) produces an out-of-bounds error for clojure; for clojurescript it returns -2 (nth (seq [3 4] -2)) produces an out-of-bounds error for clojure; for clojurescript it returns nil I expected these to fail.
I think that the clojurescript check (src/main/cljs/cljs/core.cljs line ~1763 "(not (number? n))" is not sufficient, it could also check for non-negative.
Environment
Mac OS X 10.9.5 lein 2.7.1 lein-cljsbuild 1.1.4 lein-figwheel 0.5.10 v8 5.1.281.47 Chrome Version 58.0.3029.110 (64-bit) Java 1.8.0_73 "rlwrap lein figwheel" also demonstrable on online cljs repls: http://app.klipse.tech/ http://clojurescript.io/ http://clojurescript.net/ which produce a different result than an online clojure repl, e.g.: http://www.tryclj.com/ or "lein repl"
