wc: unexpected counts for -w flag

[mknos]

• As noted earlier, word count output in wc did not match GNU version
• A word is one or more non-space characters, surrounded by whitespace (including newline)
• The old code seemed to count the spaces in between words, but I couldn't follow it
• To test this I built the OpenBSD version of wc on my linux system, then compared total word count for a set of files between OpenBSD, GNU and perl

%$wc_obsd -w s*
wc: s: Is a directory
       0 s
     524 seq
     330 shar
     319 shar2
     225 sleep
    4098 sort
    1789 spell
     895 split
wc: sssss: Is a directory
       0 sssss
     444 strings
    1116 sum
    9740 total

%perl wc -w s*
wc: 's' is a directory
       524 seq
       330 shar
       319 shar2
       225 sleep
      4098 sort
      1789 spell
       895 split
wc: 'sssss' is a directory
       444 strings
      1116 sum
      9740 total

%/usr/bin/wc -w s*
/usr/bin/wc: s: Is a directory
      0 s

changes: fix -w to report the right number
