Following on a message from a few days ago, I've prepared a patch (attached)
that alters the behavior of 'org-edit-src-exit' so that it no longer adds an
extra 2 spaces of indentation each time a source block (or a table.el table) is
edited. Previously a workaround was to set 'org-src-preserve-indentation', but
without that set, you'd get the undesirable behavior.
There's probably some stuff wrong with this approach - let me know. I'm new to
both elisp programming and the org-mode code.
I also created a little utility function 'org-prefixify', not sure whether
that's kosher or not. One change that would be nice to make to it is to avoid
prefixing the final line if it's blank, but I couldn't get that to work. Also
- could that essentially be replaced by a call to string-insert-rectangle?

Subject: [PATCH] Change the edit-src-save code so that it either preserves
original formatting, or imposes its new indentation, but
not both.
