 * DECSRIPTION
 * Tests the operation of the `repeat' commands, which print and change the status of GDB-style command repetition and
 * list auto-advance.  The particular behavior of `list' when repitition is on is tested in the `list' tests.
 * The test consists of two program:
 *   repeat001.java - launches jdb and debuggee and executes test cases
 *   repeat001a.java - the debugged application
