[Gllug] Building a patch

[Nix]

diff -ur will do that, although it's a very strange requirement.

[s/patch/diff/ as you posted]

But this is what you wanted!

diff can ignore new files in the second tree via the --unidirectional-new-file
switch. This might be what you're looking for.

Um, well, diffstat should show you that it gives you the differences
between all the others (if any), too.

(myself `diff -durN' is burned into my mind indelibly. :) )
