Agreed -- if I'd checked to see what file-remote-p actually
returned, I would done this myself from the outset.

I've tested this approach in isolation, and it works well
in my test instance.

I've not yet tested to see whether the `non-essential'
change is similarly efficient in a newer version with a
similar session.

Lars' suggestion of having these commands NOT checking
every dired buffer every time also seems very sensible.
