Probably because XEmacs was finding the (old) byte-compiled version of the efs library in the file efs.elc and loading that instead of efs.el. You don't mention that you have byte-compiled efs.el after making your edits (i.e., something like "xemacs -vanilla -batch -f batch-byte-compile efs.el" from the shell command line). Other than that, I am not sure. (X)Emacs will load the byte-compiled version of the file (.elc), if the byte-compiled file exists, in preference of the source (.el). The description of the "load" function in the "Loading->How Programs do Loading" section of the XEmacs Lisp technical reference has the details. -- Evgeny Advanced design: Upper management doesn't understand it.
