bug#6687: [24.0.50] end-of-buffer cursor position with an overlay

[Tetsuo Tsukamoto <czkmt@ims.u-tokyo.ac.jp>]

With further testings, I noticed that the condition where problem
is reproduced is not (eobp) but (and (bolp) (eolp)), i.e. when
point is at an empty line.

In addition, I should correct the conclusion of my first message as
follows.

Emacs 24.0.50 with point at an empty line displays cursor
differently relative to an overlay placed at the point.
