 I expected that...
   |  I like that, but will scripts that search for the comment be able to
   |  handle it?
 Not sure, nor am I sure what all the scripts are.   The one I use for
 kernel building which uses that value to construct the output directory
 name would not have a problem, it looks for the ' NetBSD ' in the comment
 and ignores everything before that.   But others, I'm not sure - and in
 any case, I think that should also be a separate change.
   |  Only two digits are reserved for "pp", so I think it should
   |  be restricted to [0..99].  Alternatively, remove "rr", and
   |  let "pppp" be 4 digits.
 It works either way, I just didn't want anyone to panic upon nearing
 5.99.99 and to be able to just continue on to 5.99.100 (and so on).
 It all works whether the 1 is considered as an unusual value in the r
 field or just a wider p field.   On the other hand, I can't even
 imagine the need for a 5.0.100 release (or even 5.0.10), so for everything
 other than current, 2 digits is really overkill already.
 But as I said, whatever works, just so there is some documented method
 that actually matches reality (which includes not always having 0's in the
 final 2 digit positions.)
