Hi List, 

this was posted and discussed on the Org-mode mailing list, but without
any real conclusion if it is a Bug in Emacs - or something else. So it
was suggested to repost it here. 

Say point is behind the closing parenthesis of the sexp in this Org-mode source
block:

,-------------------------------------
| #+begin_src emacs-lisp
| (+ 3 4)          # point behind sexp
| #+end_src
`-------------------------------------

Now, when I call

,-----------------------------
| M-x org-babel-mark-block RET
`-----------------------------

or

,-------------------------
| M-x org-mark-element RET
`-------------------------

the body of the source block (or the whole source-block) is (visibly)
marked as expected (transient-mark-mode is on), and 'M-w' puts the
active region into the kill-ring. 

But with the point at the same position, doing

,-----------------------------
| M-: (org-babel-mark-block) RET
`-----------------------------

or

,-------------------------
| M-: (org-mark-element) RET
`-------------------------

moves point to the beginning of source-block (body) and returns the
position of point without (visibly) marking the source-block body.
There is no region activated, 'M-w' puts nothing in the kill-ring.

bug#13724: Calling 'org-babel-mark-block' with 'M-x cmd' and 'M-: (cmd)'

[Bastien]

Let me restate the issue:

M-x mark-word RET will highlight the word at point.
M-: (mark-word) RET will *not* highlight the word at point.

My understanding was that interactive call of mark-word
highlight the region, while non-interactive call do not
highlight it.

Is this wrong?

`org-mark-element' and `org-babel-mark-block' are not
different to `mark-word' here.

Indeed, thank you.  Should be fixed now, thanks to the patch below,
