I don't know if this is a regression as the code for this error message
existed as far back as I could see in the git repository, back to 2002
(commit fc8e4fc5f364ca4f, 2002-09-03). The text in the manual has also
existed for a very long time (commit 16440098c622, 2002-08-25). It's
odd that nobody seems to have noticed this before.
It does not appear to cause any error with texi2any. It would be
straightforward to remove the error message from texinfo.tex, and resolve
the inconsistency with both texi2any and the documentation. However, since
the error message has existed in texinfo.tex for so long I will leave it
a few days to see if anybody has any other commments on the matter.
