23.0.92; Emacs 23: buffer point is no longer frame-local |

1) emacs -q (with non-nil window-system)
2) find-file /usr/share/dict/words
- any file longer than ~3x the frame height should serve to demonstrate
- in remaining steps I'll call this file buffer BUF
3) (goto-char (/ (point-max) 2))
4) (new-frame)
5) (other-frame) ; if necessary to put point in new frame
6) switch to buffer BUF
7) (goto-char (point-min))
8) switch to buffer *scratch* (or any other buffer)
9) switch to buffer BUF
Observe that point has returned to (/ (point-max) 2).
In Emacs 22, buffer point behaved as if it were frame-local:
at step 9, point would still be at (point-min).
This change may seem innocuous, but it can be quite frustrating and
mysterious if you have a multi-tty frame open at another site.
The buffer point behaves as if it's "stuck": every time you switch
away from the buffer and return, the point has returned to its
sticky position.
The behavior exhibits in both multi-tty and single-tty flavors, but
is easier to trigger in a long-running multi-tty session distributed
over multiple sites (e.g. home and work). It was serious enough to

I completely forgot about this. Any objections to install the attached
version for 24.3?
Installed. Bug closed.
