`beginning-of-defun' pushes mark undocumentedly. It shouldn't! |

Hi, Emacs!
I was "horrified" to find `beginning-of-defun' pushes the mark. OK,
maybe I should wake up, this having been done as long ago as 2004-05-01
in .../emacs-lisp/lisp.el 1.53.
However, this pushing of the mark is NOT DOCUMENTED, neither in the
Emacs nor the Elisp manual. THIS IS A BUG!!!!
This marking is fine (maybe) when a user types C-M-a. Actually, I think
it's of marginal utility - it's about as likely to be a nuisance as to
be helpful.
The marking is NOT ACCEPTABLE when begining-of-defun is used in a lisp
program. Using b-o-d in a program is a reasonable thing to do.
The feature, if it is to remain must be documented in both manuals. OK,
I'm volunteering to do this. ;-)
POSSIBLE FIXES
==============
1. A new customizable option, with a name better than
`defun-movement-leaves-mark'. This could be bound to nil by lisp
programs.
2. Document that lisp programs should use `beginning-of-defun-raw'.
(Does this exist in XEmacs?).
3. Revert b-o-d to leaving the mark well alone.
What do people think?

Closed - there is no bug. The report was a mistake.
