Hi Martin,

thanks. IMO you addressed two core-issues of Emacs' future: a political 
and a technical one.

As for the copyright, conceive it as contradicting to the idea of free 
software - whilst the paperworks reached out here rely on it.

open-paren-in-column-0-is-defun-start ignores the fact functions 
commonly might be nested.
That way Emacs can't handle nested definitions reliably.

Why not have a purely GPL-based Emacs with the 
open-paren-in-column-0-is-defun-start hampering removed?

Make Emacs still greater,

Andreas
