Hello,

Each time I edit a code block using =C-c '= (org-edit-special) and then return to the org-mode buffer, two spaces are added to the left margin of the code. For example,

#+BEGIN_SRC python

print "hello"

#+END_SRC

becomes

#+BEGIN_SRC python

print "hello"

#+END_SRC

after one round-trip. This is particularly problematic for python code blocks since leading whitespace is meaningful.

This is behavior that has been present in org-mode for so long that I suspect that it's not a bug - but I'd love to know how to disable it.

Thanks a lot,

Noah
