Redo test suite to be able to test more than one command at a time. Eliminate

$COMMAND environment variable, instead put full command line (including
command to run) in second argument.  Modify $PATH to have test versions of
commands at start of path.  (Also more infrastructure for testing as root,
work in progress...)
