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

[Tetsuo Tsukamoto]

Each (eobp) that appear in my previous message should be replaced
with (bolp), as follows.

 initial point position  :        cursor behavior
(and (bolp) (eolp))      :  0) [?]   1) [?]x   2) ?xx[]
(and (not (bolp)) (eolp)):  0) [?]   1) ?x[]   2) ?xx[]
(and (bolp) (not (eolp))):  0) ?[]   1) ?x[]   2) ?xx[]
(not (or (bolp) (eolp))) :  0) ?[]   1) ?x[]   2) ?xx[]
