[AUCTeX] Questions about TeX-auto-global

[Leon]

Dear all,

I have a few questions:

1. `TeX-auto-global' dir is always empty. 
2. What happens if this dir doesn't end with a directory separator?

,----[ TeX-auto-global ]
| TeX-auto-global is a variable defined in `tex-site.el'.
| Its value is 
| "/opt/share/emacs/site-lisp/auctex/var/auto"
| 
| Documentation:

| Must end with a directory separator.
| 
| For storing automatic extracted information about the TeX macros

Thanks,
