Function explicit_multi_path_non_text_refused 

pub fn explicit_multi_path_non_text_refused(
    paths: &[String],
    cwd: &Path,
) -> Option<Vec<PathRefused>>

Explicit multi-file lists only: non-text / unreadable co-paths that walks soft-skip.

Sole non-text is hard invalid_input via sole_explicit_non_text. Directory walks (any path is a directory) omit mass refused[] (noise). Reasons: binary, invalid_utf8, unreadable, not_regular_file.
