Convert carriage returns to newlines in reviews
Convert carriage returns to newlines in reviews

Spotbugs prints multiple lines with \r [1][2]. This looks like a single
line for shell commands but will be converted to multiple lines once
read by Python.

By performing the conversion before the tail command, we will get a
consistent line count in Bash and Python.
