Fix revert-buffer functionality of Help mode and Info.
* lisp/help-mode.el (help-mode): Set buffer-local variable revert-buffer-function to help-mode-revert-buffer. (help-mode-revert-buffer): New function. * lisp/info.el (Info-revert-find-node): Check for major-mode Info-mode before popping to "*info*" (like in other Info functions). Keep buffer-name in old-buffer-name. Keep Info-history-forward in old-history-forward. Pop to old-buffer-name or "*info*" to recreate the killed buffer. Set Info-history-forward from old-history-forward. (Info-breadcrumbs-depth): Add :group and :version.
