I'm not sure I understand. Does Emacs have a rectangle command that
does this? And if so, what is it called?

Killing the region (i.e., using `C-w') works fine for me...

I think this is way outside the scope of rectangles. Your use case
seems to be to turn a series of lines into CSV columns -- but that's
better expressed through a CSV command. You might want to group them by
two or three or four lines into columns, for instance.
So I don't think using rectangles for something like this is totally the
wrong tool, and it can't possibly work very well. Unless I'm
misunderstanding something, which I might well be doing.
