Strange behavior of (beginning-of-defun 0)

[Marcin Borkowski <mbork@mbork.pl>]

Hi all,

put this in an Elisp buffer:

--8<---------------cut here---------------start------------->8---
(defun a ()
  nil)
-!-(defun b ()
  nil)
--8<---------------cut here---------------end--------------->8---

put the point where the -!- is (of course, "-!-" is only a marker and
should not be in the buffer;-)) and say M-: (beginning-of-defun 0) (or
C-u 0 C-M-a).  The point goes up one line.

Is that intended?  Is the behavior of (beginning-of-defun 0) defined at
all?

Best,
