* window.el (split-window-save-restore-data):
Don't update the data if OLD-INFO is nil.
* view.el (view-return-to-alist): Mark it permanent local.
* subr.el (event-modifiers): Fix the criterion for ASCII control chars.
* recentf.el (recentf-save-list): Catch and warn about errors.
* menu-bar.el (menu-bar-update-buffers): Call copy-sequence
so "Buffers" won't be pure.
* help-mode.el (help-mode-finish): Set help-return-alist first
thing, setting only the entry for the selected window.
* help-fns.el (describe-function-1): If many non-control non-meta
keys run the command, don't list all of them.
