Can't reproduce the bug this morning, sorry. So maybe
forget it.

What I remember is the result of `comment-dwim' after
`mark-defun' was called:

; (defun foo (&optional arg ispec) 
;   " "
;   (interactive "*P\np")
;   (when arg (message "arg: %s" arg))
;   (if ispec
;       (message "%s" "interactive call")
;     nil)
  )

The last parenthese wasn't catched, it was set onto a
newline.

That doesn't happen any more.

Remains to notice: extension of region after of
`mark-defun' is one char larger than (substring beg
end) of function at point.

That's due to 

(re-search-backward "^\n" (- (point) 1) t)

whose possible harms may outweigh possible benefits.

Thanks all
