When lines run long and the final word or words run over the edge, and PBS squeezed them underneath the line, I've been coding this as a sublinear addition. I notice that in e1 at least, coders have decided to make the run-off word[s] a separate line, and join the two lines with a milestone tag. I would argue that the run-off words are not really a new line -- Neil uses spacings which suggest such words are in between lines rather than constituting new ones. What say you?
Lines 1 and 2 are each circled. I wasn't sure how to code this, or if there is a way.  PBS put a "2" in front of line 1 and a "1" in front of line 2 to indicate that they should be switched. I chose to use the "displacement" metamark command for this. Would this be right?
The addition in line 25 uses a caret -- wasn't sure how to code that.

Tried to treat superlinear run-off as David instructed. Hope I got it right.
