I needed a `reverse-string' function and I've found two in Org Mode. `org-babel-reverse-string' and `org-id-reverse-string'. So instead of rolling my own (I'm playing with `org-contacts.el'), I think it would be better to unify those functions into one.

Subject: [PATCH] Unify `org-id-reverse-string' and `org-babel-reverse-string'
into `org-reverse-string'
* lisp/org.el (org-reverse-string): Add `org-reverse-string' to
reverse a string.
* lisp/org-id.el: Replace `org-id-reverse-string' by
`org-reverse-string'.
* lisp/ob-core.el: Replace `org-babel-reverse-string' by `org-reverse-string'
