Fix issue 10214 by removing the out of date python-mode.el and replacing it

with a README.  Will backport to 2.7.

Misc/README.Emacs

+=============
+Emacs support
+=============
+
+If you want to edit Python code in Emacs, you should download python-mode.el
+and install it somewhere on your load-path.  See the project page to download:
+
+    https://launchpad.net/python-mode
+
+While Emacs comes with a python.el file, it is not recommended.
+python-mode.el is maintained by core Python developers and is generally
+considered more Python programmer friendly.  For example, python-mode.el
+includes a killer feature called `pdbtrack` which allows you to set a pdb
+breakpoint in your code, run your program in an Emacs shell buffer, and do gud
+style debugging when the breakpoint is hit.
+
+python-mode.el is compatible with both GNU Emacs from the FSF, and XEmacs.
+
+For more information and bug reporting, see the above project page.  For help,
+development, or discussions, see the python-mode mailing list:
