$ emacs -Q -nw file.html
Mark the <ol> to </ol> region.
Hit C-c C-o, which runs the command sgml-tag (found in mhtml-mode-map)
Enter tag name "blockquote" at the prompt, attributes: just hit RET.
The blockqute in inserted, yes. But at the same time we get the spurious

Yes. And the program indeed does the job correctly.

The problem is: but then it should not print the error message.

Because there is no error.

When the message is printed, the matching </blockquote> was not yet
inserted.

So the machinery that inserts the tag should somehow suppress this
message.  Patches welcome.
