This is a rework of the tests I alreaded posted, based on the fact
that the command is not called advance.
http://sources.redhat.com/ml/gdb-patches/2002-12/msg00585.html

I added 2 new tests, one for until, one for advance.

	* gdb.base/break.exp: Move the tests of until command from here...
	* gdb.base/until.exp: ... to here. New file. Add other tests.
	* gdb.base/advance.c: New file.
	* gdb.base/advance.exp: New file.
