* added a randomize flag and corresponding -r command line argument that

Browse Source 
allows the caller to execute the various tests in pseudo-random order -
  default is still to execute tests in the order returned by findtests().

* moved initialization of the various flag variables to the main() function
  definition, making it possible to execute regrtest.main() interactively
  and still override default behavior.

-g: generate -- write the output file for a test instead of comparing it

-s: single -- run only a single test (see below)
-r: random -- randomize test execution order
If non-option arguments are present, they are names for tests to run,
unless -x is given, in which case they are names for tests not to run.
