Hi,

Title:  `end-of-buffer' resets mark.
------------------------------------

Description:
------------

Do the following:

1. `set-mark-command'         (C-SPC)
2. `next-line'                (down)
3. `end-of-buffer'            (C-end, non-standard key?)
4. `exchange-point-and-mark'  (C-x C-x)

=> you will notice that the mark is at the point from where you
   called `end-of-buffer' and not the line above where you called
   `set-mark-command'.

,----[ C-h f end-of-buffer ]
| end-of-buffer is an interactive compiled Lisp function in `simple'.
| (end-of-buffer &optional ARG)
| 
| Move point to the end of the buffer; leave mark at previous position.
| With arg N, put point N/10 of the way from the end.
| 
| If the buffer is narrowed, this command uses the beginning and size
| of the accessible part of the buffer.
| 
| Don't use this command in Lisp programs!
| (goto-char (point-max)) is faster and avoids clobbering the mark.
`----

Does 'leave mark at previous position' mean set it to the current
point when calling?  If so, why is this implemented this way?  Or
how could it be done differently?

bars) of 2003-03-24

Question:
---------

Where can I look, whether bugs are already known (Issuezilla or the
like)?
