Ok, as an addendum, I'm finding that it doesn't even have to find a border
and it will still keep merging rows.

Which of course is why it went out so far before.

Which of course brings me back to my original idea-- it needs a start/stop
point for selecting an undefined number of rows.

Since borders are the one commonality across the board, on all instances,
and all files, I thought that'd be the best choice for my limiter element.
