This is part of the baggage in beginning-of-defun regarding whether
column zero is the beginning of a defun.  Changing this now might be
unwise, so for the moment I've simply revised the docstring of
beginning-of-defun for extra clarity.

I've also changed cc-defs.el to use beginning-of-defun-raw, which is a
more direct and side-effect free test of beginning-of-defun-function,
and added a save-excursion for extra plus safety ;-)

[Also, closing bug#636.]

Subject: 23.0.60; Read syntax error while byte-compiling
Date: Fri, 01 Aug 2008 11:43:43 +0400

The problem occurs when one tries to byte-compile a file with the
following contents (note the newline after `eval-when-compile`):

    (eval-when-compile
       (require 'cc-mode))

Using this command:

    emacs -q --batch -f batch-byte-compile file.el

Which fails with error:

    In toplevel form:
    test1.el:2:19:Error: Invalid read syntax: ")"

Visiting this file in Emacs and attempting to byte-compile it using the
`M-x byte-compile-file RET` command results in the same error being
shown in *Compile-Log* buffer.
    
In the same time, if there is no newline after `eval-when-compile`, e.g.

    (eval-when-compile (require 'cc-mode))

Byte-compiling proceeds successfully. The problem occurs only if one
requires `cc-mode`. Probably this is somehow related with `cc-bytecomp`
module.
