If a test script issues a test_done without executing any tests, for
example when using the 'skip_all' facility, the output looks something
like this:

    $ ./t9159-git-svn-no-parent-mergeinfo.sh
    # passed all 0 test(s)
    1..0 # SKIP skipping git svn tests, svn not found
    $

The "passed all 0 test(s)" comment line, while correct, looks a little
strange. Add a check to suppress this message if no tests have actually
been run.

Hi Junio,

I suspect some people would disagree with this one. Indeed, this only
irritates me when I'm feeling grumpy (so most days then). :-D
It's clearly not important (I just happened to be making changes in
this area), so drop this one if you feel it's not justified.

ATB,
Ramsay Jones
