I think copy format can be pretty unclean when the line will be longer with
multiline values or with a lot of values.  When the length of the line will
be longer than the terminal width, then searching the wanted column can be
pretty difficult.

When you know, so any value is on separate line or lines, then selection is
just primitive, and there is good enough information to find wanted data
quickly.

For this case I am working with hypothetical longer records with possible
multiline fields - just something that does chaos on the terminal, and you
want to select some part of data by mouse from the terminal screen.
