    [man pages]: Use more accurate Unix version info.
    
    The footers of the V10 man pages said "Research Tenth Edition".
    
    The headers of the V8 man pages said "Eighth Edition".
    
    Verifiably authentic V9 man pages are harder to come by, but Ninth
    Edition also lacked the "Research" term per Presotto and Ritchie's
    1990 paper "Interprocess Communication in the Ninth Edition Unix
    System".  https://www.bell-labs.com/usr/dmr/www/spe.pdf
