At the risk of being critizised by this mailing-list's QC department I
give you this (unedited) hint:

,----[ C-h v org-edit-src-content-indentation RET ]
| org-edit-src-content-indentation is a variable defined in `org-src.el'.
| Its value is 2
|
| Documentation:
| Indentation for the content of a source code block.
| This should be the number of spaces added to the indentation of the #+begin
| line in order to compute the indentation of the block content after
| editing it with M-x org-edit-src-code.  Has no effect if
| `org-src-preserve-indentation' is non-nil.

Thanks a lot, Thorsten - that's perfect. If I may provide some
suggestions/feedback to the list:

1. A more sensible value for this variable in python code blocks in
particular would be 0 if language-specific defaults are possible
(though I'll be setting my default to 0 for all languages).
2. While this variable is very well documented, it isn't very
discoverable via apropos or the html manual (at least, I wasn't able
to discover it). Perhaps a reference can be added to this variable in
the docstring for org-edit-src-code?

Best,
Noah
