One feature I would find really handy in dired is a command to diff two files against each other (maybe the ones at point and mark). One thing this would be handy for is comparing two backup files to decide whether to delete one or both of them, but of course it would have lots of other uses. Perhaps if this command were given an arg it would produce a context diff.
