 Historically, the  
 .Nm  
 utility was documented to define a word as a ``maximal string of  
 characters delimited by  
 .Aq space ,  
 .Aq tab  
 or  
 .Aq 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  
 with the documentation.  
 This implementation defines a  
 .Dq word  
 in terms of the  
 .Xr isspace 3  
 function, as required by  
 .St -p1003.2-92 .
