Wrong default setting

[Andreas Röhler]

Hi,

please notice this issue:

http://stackoverflow.com/questions/35162556/emacs-24-how-do-i-get-back-emacs-23-sexp-behavior-for-python-mode

A forward block-wise move in Python is rather like a forward-list in lisp.

As sexp is defined by syntax, this would work in Python as is, probably 
the key should not be taken.

Circumventing some emacs-bugs --when starting from inside string for 
example-- , at python-mode.el we have still py-expression for sexp.

Best regards,

Andreas
