But this method restricts the possible manipulations to those that keep the string length unchanged. That is fine for longlines, which is just swapping spaces and newlines, but it may not be very useful for other (hypothetical) purposes. Even for longlines, aset would be very inconvenient to use. _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
