ediff vs dired

Hi, The command `ediff-buffers' or `ediff-files' does not work when the dired buffer for "/tmp/" is open. It may not be a bug because there is a way to avoid the problem. For example, I can achieve it using the function definition as such as follows: (defun ediff-file-remote-p (file-name) (let ((handler (find-file-name-handler file-name 'file-local-copy))) (and handler (not (eq handler 'dired-handler-fn))))) However, I could not find out any descriptions about it in manuals except for a comment in ediff-init.el. -- Katsumi Yamaoka <yamaoka(a)jpl.org&gt;
