+Historically, the
+.Nm wc
+utility was documented to define a word as a ``maximal string of
+characters delimited by <space>, <tab> or <newline> characters''.
+The implementation, however, didn't handle non-printing characters
+correctly so that ``  ^D^E  '' counted as 6 spaces, while ``foo^D^Ebar''
+counted as 8 characters.
+4BSD systems after 4.3BSD modified the implementation to be consistent
