The documentation string for Info-default-directory says:

“Although this is a customizable variable, that is mainly for technical
reasons.  Normally, you should either set INFOPATH or customize
`Info-additional-directory-list', rather than changing this variable.”

To me, this suggests that users should prefer
Info-additional-directory-list. I guess that will change in Emacs 29,
but that is not released yet.

In any case, the documentation string for
Info-additional-directory-list says:

“List of additional directories to search for Info documentation files.
These directories are searched after those in `Info-directory-list’.”

Which is not true in the case I cited.

I am not running Emacs 29 to test, but the documentation for
Info-additional-directory-list and the code for info--manual-names do
not appear to have changed on that branch.

To be clear, I have already worked around this issue in my own
configuration.

Thanks.
