error (0, 0, _("File system loop detected; " "the following directory is part of the cycle: %s"), safely_quote_err_filename (0, ent->fts_path));
Would it be clearer to stick to just saying "cycle" or "loop" but not using both words? I'm just considering that we may be making it harder to understand the error message. It also might make it unobvious to translators (who might wonder whether using different words was part of an important distinction).
