Paul, can you double-check the result you are getting from (format "'%-9s'"
"12345") ?
For example, wrap it in a call to count, i.e. (count (format "'%-9s'"
"12345")). I get the expected string back from format, and the expected
length of 11 characters, on all of these Clojure/JVM/OS combos I tested:
Mac OS X 10.8.5 + JVM 1.7.0_51 + Clojure 1.5.1
Mac OS X 10.8.5 + JVM 1.7.0_51 + Clojure 1.6.0
Ubuntu Linux 12.04.4 + OpenJDK 1.6.0_30 + Clojure 1.5.1
If you are still getting incorrect results, what combination of software
versions are you using?
