This won't work at the level of functions but I've found diff -c output
to be nice to use with acme. It assumes no spaces in filenames, :)
I don't suppose everyone has Erik's rc patch yet.

!#/bin/rc

fn cd

flist = `{@{cd B && du -a | awk '{print $2}'}}

for(f in $flist) {
	if(test -e A/$f) {
		diff -c A/$f B/$f
	}
	if not {
		echo B/$f':	new file'
	}
	echo
}
