But, some people like short output.   If you have lots of output with 
lots of tests it becomes really hard to see where one test starts and 
the next one ends.  So, there would have to be two different types of 
targets.  However, I think this thread is about yet another way someone 
wants the tests to work.  In this case, I think that the verbose output 
is only wanted for tests that fail.  It is not going to be possible to 
make everyone happy....
