Subject: [PATCH] removing code block, results and call-line synonyms -- BREAKING CHANGE

Following a round of on-list discussion many code block synonyms have
been removed, moving forward the following syntax is valid.

- call lines are specified with #+call:
- code blocks are named with #+name:
- results are named with #+name:, however results generated by a code
  block may still be labeled with #+results:, and tables named with
  #+tblname: will be considered to be named results

The following function may be used to update an existing Org-mode
buffer to the new syntax.

  (defun update-org-buffer ()
    "Update an Org-mode buffer to the new data, code block and call line syntax."
    (interactive)
    (save-excursion
      (flet ((to-re (lst) (concat "^[ \t]*#\\+" (regexp-opt lst t)
                                  "\\(\\[\\([[:alnum:]]+\\)\\]\\)?\\:[ \t]*"))
             (update (re new)
                     (goto-char (point-min))
                     (while (re-search-forward re nil t)
                       (replace-match new nil nil nil 1))))
        (let ((old-re (to-re '("RESULTS" "DATA" "SRCNAME" "SOURCE")))
              (lob-re (to-re '("LOB")))
              (case-fold-search t))
          (update old-re "name")
          (update lob-re "call")))))

Note: If an old version of Org-mode (e.g., the one shipped with Emacs)
      is installed on your system many of the important variables will
      be pre-defined with a defvar and *will not* have their values
      automatically updated, these include the following.
      - org-babel-data-names
      - org-babel-result-regexp
      - org-babel-src-block-regexp
      - org-babel-src-name-regexp
      - org-babel-src-name-w-name-regexp
      It may be necessary to either remove the source code of older
      versions of Org-mode, or to explicitly evaluate the ob.el file.
