Remove RCS keywords 2004-04-10 Miles Bader <miles@gnu.org> RCS keyword removal (only non-comment changes are enumerated here): * lisp/emacs-lisp/bytecomp.el (byte-compile-version): Variable removed. (byte-compile-insert-header): Don't use `byte-compile-version'. * lisp/url/url-vars.el (url-version): Use the constant string "Emacs" instead of calculating something from the RCS `State' keyword [the latter is almost entirely useless anyway]. * lisp/forms.el (forms-version): Variable removed. (forms-mode): Don't use `forms-version'. * lisp/recentf.el (recentf-version): Variable removed. * lisp/progmodes/delphi.el (delphi-version): Variable removed. * lisp/progmodes/ada-mode.el (ada-mode): RCS keyword removed from docstring.
