Right. But that's probably what you want because the same thing
will happen to all the other individuals in the group. It works
the same way if there's some temporary interruption in observation
of a group, group membership is interpolated forward, and then
again when observation is resumed.
Note that if you want to "nail down" a date and not have it
interpolated you can use the 'N' manual census Status code.
(FWIW on the cleanup list is probably a review of the
existing M and N code use. Daphnie put a lot in
when the interpolation was broken in Babase 1.0 (foxpro)
in order to get the result to look right.)
