[Q] Change forms like (delq nil (mapcar ...)) to (mapcan ...).

QUERY Aidan Kehoe writes: This can't work as written, can it? If X is nil, if Y is nil, it will wrap nil in a list and the nil will not be deleted. I guess from a quick look at the patch that it's expected that if X is non-nil, Y will be non-nil, but are you sure? I'm also not convinced that this is necessarily faster if (length Z) is small, as the mapcan version involves extra consing. _______________________________________________ XEmacs-Patches mailing list XEmacs-Patches(a)xemacs.org http://calypso.tux.org/mailman/listinfo/xemacs-patches
