commit 2d0ff6aa5d6951aaa00e2d6cf3878788b025983e

    Related fdo#43895: Fixed shortcommings of FileDialogHelper_Impl::verifyPath
    
    * maPath.reverseCompareToAsciiL("file:///tmp",11) == 0 failed for file:///tmp/
    * It was unclear whether special treatment should only happen for files directly
      in /tmp or also in sub-dirs; assuming the latter now.
    * Proper translation from file URL to system path.
