The summary line should be shorter.  Also you need to add a reference to
the function being modified, e.g.,

* list/ob-ref.el (org-babel-ref-parse): Make sure the buffer pointed by...

Eventually, you need to add "TINYCHANGE" string at the end of the commit
message if you haven't signed FSF papers.  See
<http://orgmode.org/worg/org-contribute.html#orgheadline8> for details.

This won't work as `org-babel-read' is not called within the scope of
`with-current-buffer'.

I think it should be something like this:

  (with-current-buffer
      (if (markerp org-babel-current-src-block-location)
          (marker-buffer org-babel-current-src-block-location)
        (current-buffer))
    (save-excursion
      (goto-char org-babel-current-src-block-location)
      (org-babel-read ref)))

Bonus points if you can write a test about it in "test-ob.el".
