Re: [RFA] Handle output after 'Program exited normally' consistently (detect spurious output)

I modified the a2-run.exp test to allow it to run the part of the test that
doesn't require being able to pass arguments, and detect spurious output
after the program exits normally.  Patch below.

 	* gdb.base/a2-run.exp: Allow part of test to run when args aren't
 	required.  Check for spurious output after program exits normally.
