Which means that each version of Emacs you tried displayed a different
elisp.info file.  And that in turn means that you need to look at each
of those elisp.info files to see whether they have DOS EOL format
and/or were produced by the problematic versions of Texinfo mentioned
in the bugs whose numbers I cited a few messages back.  If you still
want to understand what happened to you with the previous versions o0f
Emacs, that is (from my POV if it doesn't happen in the current
release branch, there's no reason to look into this any longer).

The issue is not what you did, the issue is what actually happened.
And again, you asked the question about my being able to explain what
happened to you with the other Emacs versions.  I'm just trying to
help you understand that.
