Hi,
It is convenient to use mark-ring to retrieve different places in a
buffer.
Using the global-mark-ring is a little bit more inconvenient because
once it have recorded a position in a buffer, it doesn't update this
position if user set the mark in another place in this buffer.
Is there a particular reason to not update this new position ?
I would prefer something like this:
--8<---------------cut here---------------start------------->8---
diff --git a/lisp/simple.el b/lisp/simple.el
index 138c242..c831a29 100644
--- a/lisp/simple.el
+++ b/lisp/simple.el

(if (and global-mark-ring
(eq (marker-buffer (car global-mark-ring)) (current-buffer)))
;; The last global mark pushed was in this same buffer.

+ (setcar global-mark-ring (copy-marker (mark-marker)))
(setq global-mark-ring (cons (copy-marker (mark-marker)) global-mark-ring))
(when (> (length global-mark-ring) global-mark-ring-max)
(move-marker (car (nthcdr global-mark-ring-max global-mark-ring)) nil)
