/index shows names as the log does, one line of UTF-8, and a newline in a name as \n

/index printed a name as it was, so a directory with a newline in it split
its row in two, and bytes not UTF-8 went through; the log turned the
newline into a space, silently another name. Both now show a name one
way: a newline `\n`, other controls, DEL and C1 a space, bytes not UTF-8
`\xNN`.
