fix handling of gopher selectors Much of telescope works in terms of URI, so we convert each gopher link to an URI. However, we didn't urlencode the path parameter, thus failing on every link that contains spaces or similar invalid (in URI paths) characters.

work around a possibly missing LINE_MAX

move all the sources back in the root directory subdir is just messier for no good reason
