* src block: 'C-c C-c can do nothing useful here' if cursor on blank line

Perhaps this is the intended behavior, but I noticed that I go to
execute a code block and get the message "C-c C-c can do nothing
useful here" if I'm not on the actual src block definition or a line
of code. If I'm on a blank line inside it, it doesn't execute. Here
was my test:
#+begin min_config
(add-to-list 'load-path "~/.elisp/org/lisp/")
(add-to-list 'load-path "~/.elisp/org/contrib/lisp")
(org-babel-do-load-languages
'org-babel-load-languages
'((R . t)))
#+end
Start with =emacs -Q= and then =M-x load-file RET
~/path/to/min-config=, then use this test file:
* heading
#+begin_src R
^
x <- 1:10
x
#+end_src
With the cursor at ^ it won't run. I would understand if this were in
interactive mode using =C-c '=, but the behavior of C-c C-c is to run
the whole block anyway. It seems like Org doesn't know I'm in a src
block. Since blank lines are common, I'd expect not to have to make
*sure* I'm on an actual line of code and that being anywhere in a src
block should work.
Thoughts?
Thanks,
John

I have noticed this recently as well. Not sure if it was always the
case, mind you, but it would be nice if C-c C-c would work even when the
cursor is on a blank line (within a src block, that is).

I get this all the time too. It would be nice if it went away, I also
find it annoying.

I think this changed with 0b6a2e241 (C-c C-c does nothing when at a
blank line, 2013-02-15). I wasn't able to figure out the motivation for
that change.

Nor I. Perhaps it was just an oversight.
FWIW, in `org-ctrl-c-ctrl-c'
: (looking-at-p "[ \t]*$")
could be
#+BEGIN_SRC emacs-lisp
(and
(looking-at-p "[ \t]*$")
(not (eq 'src-block (org-element-type (org-element-context))))))
#+END_SRC
without causing a lot of grief. I think `src-block' is the only
relevant case.

In almost all cases, you don't want C-c C-c to do anything on a blank
line. Commit 0b6a2e2416b0acc28469661d7013f92f82a34267 pointed out before
was pushed because calling C-c C-c on the blank lines right after
a blank line would call `org-set-tags'.
What you suggest is sub-optimal, tho. The point of this quick check is
to eschew `org-element-context' call a few lines below. This would make
two calls instead of one.
I think a proper solution is to bite the bullet and make the check after
calling `org-element-context', in a pcase branch. This is what I did in
ebb9da0d0.
Please let me know if it doesn't solve the issue.
Regards,
