On second thought there's also the format discrepancy.  Right now the
new uname crates the version string like "10.0-17763", but it might be
better to use "10.0.17763", replacing the dash with a dot, to follow
more closely the OS layout.  On third thought it seems prudent to
print either

  10.0-1809{-WOW64}

or

  10.0.17763.253{-WOW64}


Hmm.  The second form appears to make the most sense, actually.
