[Stefan Kangas]

branch: master
commit 80fddff5d64ff915651eb751685b7430de00c536
Author: Stefan Kangas <stefan@marxist.se>
Commit: Stefan Kangas <stefan@marxist.se>

    Clarify define-derived-mode docstring
    
    * lisp/emacs-lisp/derived.el (define-derived-mode): Doc fixes;
    correctly mention that the mode name is used in the mode line, clarify
    argument types, and how the mode hook is named.  (Bug17567)
    
    (derived-mode-hook-name, derived-mode-map-name)
    (derived-mode-syntax-table-name, derived-mode-abbrev-table-name):
    Clarify that argument is a symbol.
