Good suggestion.

I rarely (if ever) use "-x" myself but another useful thing to know,
while learning how the existing test works (i.e. studying a working
test, not debugging a broken test) is to use "-d", possibly together
with "-v", which refrains from removing the trash directory.  Then
you can go in and examine the state of the test repository the tests
left.

Thanks.
