I think diff -u is better when the goal is to show just the differences, but diff -c is better for changes in the middle of non-trivial code.
Different people have different preferences, but I need diff -c. diff -u is always hard for me. Since `default-frame-background-mode' is not a user option, but an internal variable, then maybe it should be mentioned under the `Lisp Changes in Emacs 22.1' section of etc/NEWS? I didn't know it was an internal variable. That being so, this shouldn't be mentioned in NEWS. The only user-level impact of this is to fix a bug, and we don't mention bug fixes in NEWS. _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
