[O] org-babel-expand-src-block behavior

[Ken Mankoff]

Hi,

I've just learned about =org-babel-expand-src-block= (from [1]) which seems 
like an improvement over =org-edit-special=, because variables are expanded.

But I notice two issues with it, and I'm wondering if these are intentional or 
bugs, or if there are work-arounds.

First, the buffer is read-only (which someone else claims is a bug [2]), and 
second, if I make changes and then exit the expanded block (via C-') without 
saving, the changes are lost. If I enter =org-edit-special= and exit w/o 
saving, the changes are propagated back to the buffer.

Cheers,

  -k.
