Yes, I meant at EOB.

By that reasoning, line-number-mode (the %l construct) should be changed
so as not to display a number when point is at EOB.  Perhaps it should
display "EOB" or "END" instead.

It's not a big deal for sure, though it seems at first sight unintuitive
that if the buffer ends with a sequence of newlines, all but the last
will be numbered (especially when the last one is also numbered in the
mode line).
