bug#13796: 24.3.50; Minor bug in "(elisp) Managing Overlays"

[Xue Fuqiao]

In (info "(elisp) Managing Overlays"):

 -- Function: move-overlay overlay start end &optional buffer
[...]
     This is the only valid way to change the endpoints of an overlay.
[...]

 -- Function: remove-overlays &optional start end name value
     This function removes all the overlays between START and END whose
     property NAME has the value VALUE.  It can move the endpoints of
     the overlays in the region, or split them.

I think both `move-overlay' and `remove-overlays' can change the
endpoints of an overlay.  So maybe it is a bug here.
