run-tests: unnecessary globs also count as warnings
When a glob is unnecessary, now there's a diff output and 'run-tests.py -i'
works for accepting the output.
On windows, some tests which have "passed" currently (with some info lines
printed) will now be reported as "warned". (I recommend to recognize "warned"
by buildbot before applying this patch.)
