bug#15069: [PATCH] Bug: 15069: Correct functioning in the *scratch* buffer

[pillule]

Hi,

Is that correct that it is a documentation bug (need to specify to 
the user to evaluate `count-words-in-defun' in eg, a *scratch* 
buffer) rather than an implementation bug (fixing the behavior of 
beginning-of-defun in Info-mode) ?

If so I attached a small patch there, and verified it after a 
`make docs`

0001-Clarify-page-14.3-of-eintr-manual-bug-15069.patch
Description: patch for the emacs-lisp introduction manual

I remember I especially liked to be able to evaluate sexp in place 
in the eintr manual, that is fitting so well the interpreted 
nature of elisp, but here the situation is out of my mind :
- 1. the norm seems to *not* use the column 0 to declare top 
level sexp in Info manuals even if 
`open-paren-in-column-0-is-defun-start' is set to t.
- 2. there is many opened sexp given as exemple, which will 
confuse the syntaxe tree.

Have a nice day, or, night, I don't know.
