123Historically, the
124.Nm
125utility was documented to define a word as a ``maximal string of
126characters delimited by <space>, <tab> or <newline> characters''.
127The implementation, however, didn't handle non-printing characters
128correctly so that `` ^D^E '' counted as 6 spaces, while ``foo^D^Ebar''
129counted as 8 characters.
130.Bx 4
131systems after
