Replace echo -e with printf

This script uses `#!/bin/sh` as its shebang, which means it expects a
POSIX-compliant shell. However, it also uses `echo -e` which is not
POSIX-compliant[0].

Rewrite `echo -e "$arg"` invocations to `printf "$arg\\n"` so that
the script is brought into POSIX compliance.
