Hi Sam, I am sorry for the late reply. It seems I forgot to apply the patch I originally sent. I have just done so.
It seems like what you are talking about below is a different problem, though. The ‘org-src-in-org-buffer’ macro is only called when saving or tangling, not when invoking ‘org-edit-special’ (C-c '). And at least in a quick test, I do not see any buffer corruption when saving (C-c ' C-x C-c '). Do you? Thanks, -- Aaron Ecay
