Since #23493 has conflicts with latest commits, this PR is my proposal for fixing #23371 Details are in the comments And refactor the `modules/options` module, to make it always use "filepath" to access local files. Benefits: * No need to do `util.CleanPath(strings.ReplaceAll(p, "\\", "/"))), "/")` any more (not only one before) * The function behaviors are clearly defined
