The XEmcas Lisp Reference Manual section about signals and errors should probably be updated to reflect that. Here is a quote from the section describing error: `error' works by calling `signal' with two arguments: the error symbol `error', and a list containing the string returned by `format'. And a quote from the section describing signal: The function `signal' never returns (though in older Emacs versions it could sometimes return).
