One look logs one err: a file:addr whose file is not there is one miss quoting what was written, and a refused placement is the look's only failure

A look at utf8txt:#3 from a terminal searched for utf8txt, missed, then found the terminal no text to address: two errs for one write. It is now looked for whole, as zzq:2 already was, so every form's miss reads no match for "<as written>". A look whose new pane was refused a place went on to settle its line in the pane it stayed on and logged has no line N after the placement failure; it now stops there.
