[9.5.4 (release_9.5.4 @ /usr/local/share/emacs/29.0.50/lisp/org/)]

When trying to create a new src-block via `M-x
org-babel-demarcate-block` immediately after a previous code block (only
empty lines in between), then the command behaves like when splitting a
src-block (inserting an #+end_src first, followed by a #+begin_src).

However, as the point is outside of the source block, according to the
docstring of the command, a new source block should be created.

As a comment, normally when creating a new source block, Emacs prompts
for the source block type. However, currently, when used as mentioned
here, the command automatically sets the type (because it tries to
split). I would say that is convenient behavior, so that effectively
only the order of the inserted lines should get reversed.

In any case, thanks for the amazing work!
