Thanks for proofreading! Attaching the fixed version of the patch.

Subject: [PATCH] Auto-Upcase/downcase #+begin/#+end in structure templates

* lisp/org-tempo.el (org-tempo-add-block):
* lisp/org.el (org-insert-structure-template): When inserting
 #+begin_type/#+end_type, follow type's case.  TYPE will become
 #+BEGIN_TYPE and type will become #+bein_type.

(org-insert-structure-template): Make sure that we use
case-insensitive match even when user changes case-fold-search value.

(org-structure-template-alist): Clarify selection of #+BEGIN/END
vs. #+begin/end in the docstring.
