Well, it's certainly in the calls to it from simple.el:

grep --color -nH -e "line-move-1" `find . -name '*.el'`
./simple.el:5930:         (line-move-1 arg noerror to-end)
./simple.el:5941:;; This is like line-move-1 except that it also performs
./simple.el:5955:      (line-move-1 arg noerror to-end)
./simple.el:5997:       (line-move-1 arg noerror to-end)))))
./simple.el:5999:;; Display-based alternative to line-move-1.
./simple.el:6071:(defun line-move-1 (arg &optional noerror _to-end)

I'll remove those from the calls, but I think the _to_end parameter will
have to remain in the -1 function.
