Subject: [PATCH] Only strip trailing dots and spaces on Windows

NormalizeFileName() removed trailing dots and spaces from every path
component on all platforms, but that restriction only applies to
Windows filesystems. On Linux and macOS it silently mangled folder
and file names ending in a dot (e.g. "Bach J.S." became "Bach J.S").
