fix so that CL docstrings (with &key, etc.) handled properly -------------------- ChangeLog entries follow: -------------------- lisp/ChangeLog addition: 2010-02-23 Ben Wing <ben@xemacs.org> * autoload.el: * autoload.el (make-autoload): * cl-macs.el (cl-function-arglist): * cl-macs.el (cl-transform-lambda): Don't add argument list with the tag "Common Lisp lambda list:"; instead add in "standard" form using "arguments:" and omitting the function name. Add an arg to `cl-function-arglist' to omit the name and use it in autoload.el instead of just hacking it off. * help.el: * help.el (function-arglist): * help.el (function-documentation-1): New. Extract out common code to recognize and/or strip the arglist from documentation into `function-documentation-1'. Use in `function-arglist' and `function-documentation'. Modify `function-arglist' so it looks for the `arguments: ' stuff in all doc strings, not just subrs/autoloads, so that CL functions get recognized properly. Change the regexp used to match "arguments: " specs to allow nested parens inside the arg list (happens when you have a default value specified in a CL arglist).
