That seems somewhat confusing to me. Intuitively, I would expect the new
page to start after the delimiter, not immediately before it

For comparison, when (looking-at-p "$") returns non-nil, that means
point is at the end of the current line (i.e. before the "\n"), not the
beginning of the next one. (Of course, they're not exactly the same,
since page-delimiter can match multiple characters.)
