Behave better when #'variable-at-point gives nil, #'custom-variable-prompt. lisp/ChangeLog addition: 2009-09-27 Aidan Kehoe <kehoea@parhasard.net> * cus-edit.el (custom-variable-prompt): nil is a symbol, check that variable-at-point is non-nil before checking if it's a symbol when deciding on the prompt used in this function.
