Hi

I started using org babel for python, but when using C-c ' I always
ended up with white space added to the empty lines in the source code
when returning into the org buffer. This especially shows up
(setq-default show-trailing-whitespace t).

I tried to fix this in org. It seems to work over here, but my elisp as
well as my understanding of org-mode is not perfect ;) Let me know if it
needs more work.

Arun

Subject: [PATCH] lisp/org-src.el: don't add indent for empty line when exiting
 a code edit

Using C-c ' to edit code blocks adds an indent to all lines when exiting from
the code edit. This leaves trailing whitespace in the buffer, which can be especially
annoying when using show-trailing-whitespace.
