Does xemacs support ACLs?

While reading http://www.gurulabs.com/RedHatLinux9-review.html, I noticed this quote: Just a quick observation. The way text editors save files normally, is to create a new file with a temporary random name, and then move/rename the new file to name of the original. Using this technique, if the file being edited has ACLs, the ACLs will be lost. The Vim editor uses libacl to obtain the original ACLs, and then add them back after the save. It is important that other applications that save files in the same fashion are updated to use libacl. Does this impact xemacs?
