tests: inform on Windows about unnecessary glob lines When glob lines directly match on windows, "/" (and not "\") was output in the path on the line. No glob matching is necessary in this case. The test output will look like this (when 5 tests have passed and no 4 has an unnecessary glob): ... Info, unnecessary glob: info about some/thing (glob) ..

tests: quickly check if the glob line already matches the output This happens when a path with "/" as only glob char is matched on a non windows platform. (Currently one third of all glob matches.) The slowdown on windows and the speedup on other os are neglectable.

tests: append glob to filename output when required (windows) This lines were introduced in cd403d6d96ef and made the test fail on windows.
