At present the 'ut' command handles its flags in a strange way, in that
they must come after the subcommand.
So, we must use 'ut bloblist -r2' to run the bloblist tests twice. This
is an artefact of the way tests were run, through subcommands.
It is now possible to correct this, by doing flag-processing before
running the suite.
Update the code to handle this, so that 'ut -r2 bloblist' works. Update
the 'test_suite' test to check the new arguments.
Add a sanity-check for -I while we are here.
