operates on, but that is entirely the programmer's responsibility.
@xref{Positions}, for a complete description of positions.
- A marker has two attributes: the marker position, and the marker
-buffer. The marker position is an integer that is equivalent (at a
-given time) to the marker as a position in that buffer. But the
-marker's position value can change often during the life of the marker.
-Insertion and deletion of text in the buffer relocate the marker. The
-idea is that a marker positioned between two characters remains between
-those two characters despite insertion and deletion elsewhere in the
-buffer. Relocation changes the integer equivalent of the marker.

@cindex marker relocation
Deleting text around a marker's position leaves the marker between the
