    contrib/hdtbl/examples/*.roff: Seed RNG.
    
    Support reproducible builds by seeding hdtbl's random number generator
    (in contrib/hdtbl/examples/common.roff).
    
    When A/Bing roff documents after a build to see what I broke with my
    changes, I always have to ignore the numerous color changes caused by
    contrib/hdtbl/examples/common.roff seeding its random number generator
    with the current date/time and process ID.
    
    Zeroes turned out to be bad seeds; the tables didn't have much in the
    way of color gradients.
