Double quote variables to prevent globbing and word splitting
This change goes through and quotes variables where appropriate to avoid issues with incorrect splitting. The performance tests ran into an issue with $SUDO_COMMAND splitting incorrectly because it was not quoted. This change fixes that issue and hopefully gets ahead of any other similar problems.
