I'm running on Mac OS X Sierra with Clojure 1.8.
I have to admit that behavior when trying to read a long line in
terminal/repl is a bit odd (it may be the limitation of terminal).
However, If I try this via input from the text file it works properly:
wc -c very-long-line.txt
8101 very-long-line.txt
java -cp
/Users/jumar/.m2/repository/org/clojure/clojure/1.8.0/clojure-1.8.0.jar
clojure.main read-line.clj < very-long-line.txt
8100
Note: I actually put 8100 chars into the file, so 8101 reported by wc
probably includes new line character.
