Is `dired-directory' really the right test here?  I am used to seeing
(derived-mode-p 'dired-mode) for that purpose (assuming I understand the
purpose here).

There is, BTW, nothing in the doc string of `dired-directory' that says
what a nil value means.  Should code now instead be using
`dired-directory' to test whether the mode is (derived from) Dired?

If so, then at the very least the doc string of that variable should
describe such a Boolean meaning: nil means not in Dired mode or a mode
derived from it (or whatever the completely correct interpretation is).
