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.
