test harness for C<use x.xxxx>

Here is the test harness for version numbers in use statements. It
checks both the C<use x.xxx> and C<use MODULE x.xxxx>

Paul suggested in an earlier message, the introduction
of a pragma directory. I would suggest that this test
should also go in the pragma directory.
