Indeed. But what you perhaps don't realize is that in this case what
is shown on the last screen-full is not EOB, but BOB! That's because
everything is reordered for display, so the first character appears
last.
I've fixed some more issues with such (relatively rare) situations, so
now these commands should work more reasonably (but very slowly) after
C-f in that file.
