This would also explain why screen-lines.el (not part of Emacs)
stopped working correctly at about that point in time.

There are other packages that rely on the old behavior, and the
doc-string might have been interpreted to guarantee it:

    Move point to start of the screen line LINES lines down.

To me, that implies that a value of zero for LINES should move point
to the start of the current line.
