Hi Chris,
You have touched upon a true limitation in the current tangle
functionality. I think this issue has two parts (one of which you
address below).
1) it is impossible to specify a piece of heavily indented code in a
source-code block. For example
--8<---------------cut here---------------start------------->8---
#+begin_src python
9
#+end_src
--8<---------------cut here---------------end--------------->8---
will always be exported as
--8<---------------cut here---------------start------------->8---
9
--8<---------------cut here---------------end--------------->8---
because Org-babel strips off any leading spaces. This problem is
exacerbated by the fact that C-' org-edit-special also strips off
leading spaces.
2) There is no way to specify the level at which the contents of a
source block should be indented. You provided a good solution to
this second issue below, and I'm adding it to the org-babel task
stack.
Thanks -- Eric
