I disagree with one point in this interesting and thoughtful post.

The post goes on to suggest that under option "nospaces" a data line
consisting of an underbar followed by a space should be interpreted
as if it had been a bare underbar, signifying a line across the whole

I agree that an underbar followed by a space qualifies as a data item.
However, the man page clearly distinguishes between "data item" and
"data line". Ignoring spaces in a data item does not destroy its
itemhood. It does not magically become a data line.
