All test scripts to be executed are now named as T\d\d\d-name.sh,
numers in increments of 10.
This eases adding new tests and developers to see which are test scripts
that are executed by test suite and in which order.
The choice of decreasing timestamps is a hack which reduces the number
of existing tests which fail. This can be changed to increasing
if/when somebody wants update another 47 tests.
Systematically test the exclude options for search. Also move the
search existing exclude tests into the new test. There is some overlap
between the two sets of tests but many of the existing ones are there
because they triggered bugs in the past so I have kept them to ensure
coverage.
