; sous xemacs, visit-tags-table n'a pas d'argument optionnel. Sous gnu emacs :
; Normally M-x visit-tags-table sets the global value of `tags-file-name'.
; With a prefix arg, set the buffer-local value instead.
; mieux vaut sous gnu emacs gérer la variable tags-table-list, qui
; n'existe pas sous xemacs.
; Sous xemacs il faut gérer la variable tag-table-alist qui n'existe pas
; sous gnu emacs.
