Hi folks,

Info.el gives the following advice for customizing the Info manual
search path:

"Normally, you should either set INFOPATH or customize
`Info-additional-directory-list' ..."

The variable Info-additional-directory-list is intended as the main
Lisp-level customization point for users. Its documentation states:

"These directories are searched after those in `Info-directory-list'."

Unfortunately, it is not used consistently across info.el.

In particular, the info--manual-names routine does not respect the
Info-additional-directory-list variable. While this function is internal
to the package, it is used to generate candidates for completing read in
some commands.

Here is a recipe to demonstrate the problem:

1. mkdir -p /tmp/emacs
2. touch /tmp/emacs/example.info
3. emacs -Q
4. M-: (setq Info-additional-directory-list '("/tmp/emacs/")) RET
5. C-h R exam TAB

Observe that there are no completion candidates.

6. C-g
7. M-: (add-to-list 'Info-directory-list "/tmp/emacs/" 'append) RET
8. C-h R exam TAB

Observe that there are completion candidates for the example info file as
expected.

There may be other instances where Info-additional-directory-list is
ignored. For example, I see that the Info-read-node-name-1 function
references Info-directory-list but not Info-additional-directory-list.

Thanks!
