When printed (yes, printed, on dead trees), those are page breaks (i.e.,
a command to continue printing on a new page). Also, Emacs has "page"
commands (e.g., count-lines-page, forward-page) that work on "page"s of
text between page breaks.
This seems to hage come up recently as well; perhaps this list's archive
has more information.
