commit 4f1cfe61ede418f795095c2d3c021db64c860e20

    Let users' PATH decide which groff suite to pick up.
    
    Let groff pass the -c flag to grotty, which will turn off ANSI
    sequences. While these are not a problem for our more/less, they get
    mangled by col(1) and this will result in garbage output.
    
    This makes man(1) work together with textproc/groff, in case the
    user decided to delete the old groff from base (-DWITHOUT_GROFF).
