Hmm, well I had used that for at least a week before posting, but I have
now noticed a problem. It's a bit of a corner case. If you create extra
blank lines at the end of the source code edit buffer and leave point
down there, then do org-edit-src-exit, now back in the org buffer point
is outside the source code block. In that case, the code that I just
posted doesn't work. I suggest that org-edit-src-exit should in this
situation place point at the end of the source code block, for example
like this:


diff --git a/lisp/org.el b/lisp/org.el
index 659dfad..be459b5 100644
--- a/lisp/org.el
+++ b/lisp/org.el

   (if (looking-at "[ \t\n]*\n") (replace-match ""))
-  (if (re-search-forward "\n[ \t\n]*\\'" nil t) (replace-match ""))
+  (when (re-search-forward "\n[ \t\n]*\\'" nil t)
+    (replace-match "")
+    (setq line (min line (org-current-line))))
   (when (org-bound-and-true-p org-edit-src-force-single-line)
     (goto-char (point-min))
     (while (re-search-forward "\n" nil t)
