Double quote variables to prevent globbing and word splitting

Browse Source 
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.
