Subject: [PATCH 269/398] sc lok: avoid placeholder row when providing all
 headers

In case the logic visible area is known, info is provided only about the
visible headers. Given that only relative sizes (no absolute positions)
are provided, a placeholder row/col is added to the result that contains
the total size of the skipped items.

These placeholder items are not needed when providing all headers, so
don't emit them.

(cherry picked from commit 788cec0a60dcfce6d86c820e9d0f7a1eb634f7bf)
