name takes any byte a file name can hold, controls, edge blanks and bytes not UTF-8 included, so what name reads writes back as it was

A pane opened on a file whose name held a tab, a control byte or bytes
not UTF-8 read that name from its name file, and the same bytes written
back were refused. Only what no file name holds is refused now: a second
line and a NUL. The ctl word name still refuses a second blank after the
word, as a line's words are split at blanks.
