A file name with a newline is refused naming it once: `pardes: two\nlines.txt: a file name is one line...`, not `a file name: a file name ...`

The refusal's subject was the words "a file name", and its reason
began with them again. It now names the name given, its newline shown
`\n`, as /log and /index show one.
