Hello, Team!

It seems that in ox-texinfo.el the `string-match-p' is used instead of
`string-equal' (here is my patch):

--- /usr/local/share/emacs/30.0.50/lisp/org/ox-texinfo.el.gz
+++ #<buffer ox-texinfo.el.gz>
@@ -1680,7 +1680,7 @@
   "Transcode a SRC-BLOCK element from Org to Texinfo.
 CONTENTS holds the contents of the item.  INFO is a plist holding
 contextual information."
-  (let* ((lisp (string-match-p "lisp"
+  (let* ((lisp (string-equal "lisp"
 			       (org-element-property :language src-block)))
 	 (code (org-texinfo--sanitize-content
 		(org-export-format-code-default src-block info)))

Without this fix I can't export my `.org' files to `.texi' format as the
:language property is nil for #+BEGIN_EXAMPLE ... #+END_EXAMPLE blocks.

`string-match-p' is used there on purpose to mark lisp, emacs-lisp, and
even elisp blocks with @lisp Texinfo markup.
See https://www.gnu.org/software/texinfo/manual/texinfo/texinfo.html#g_t_0040lisp

`org-texinfo-src-block', which you modified in your patch, has nothing
to do with example blocks. It only handles exporting src blocks
(#+begin_src .. #+end_src).

Example blocks are exported using @example Texinfo markup.
See https://www.gnu.org/software/texinfo/manual/texinfo/texinfo.html#g_t_0040example
Example blocks have no notion of language in Texinfo.

Please describe your problem in more details. What do you mean by "can't
export"? See https://orgmode.org/manual/Feedback.html#Feedback

Thanks!
I fixed this and similar problems on main.

Fixed.
