[Babase] Blanks in Neighbors tables

Hello Karl,
While working on conversion errors I noticed a small issue with the
neighbors tables. There are a few rows in FPNEIGHORS and JPNEIGHBORS
that have no neighbor associated with the row. There is a blank in both
the Sname column and the unkid column. I think that these rows should be
deleted. I wanted to check to see if deleting these makes sense and also
see if there is a rule in BABASE about this particular situation. The
documentation says "One and only one of these columns may contain a
value, the other column must then contain NULL." but does not address
the situation of both being NULL. Maybe we want a rule that does not
allow both columns to simultaneously be blank. There are approximately
10 rows where this occurs.
Thanks,
Leah
