When we taught read_directory_recursive() to recurse into untracked
directories in search of ignored files given DIR_SHOW_IGNORED_TOO, that
had the side effect of teaching it to collect the untracked contents of
untracked directories. It does not make sense to return these, so we
teach read_directory() to strip dir->entries of any such untracked
contents.
