(dired test-dir) reverts an existing Dired buffer, because of setting
dired-auto-revert-buffer to t.  (When I step through the code, it is
after reverting that point moves to the subdirectory line, which the
should make "sanity check" true (and does, both when I step through the
code and just run the test in any way).  When I comment out the
dired-auto-revert-buffer line, then point stays at point-min, which
makes the sanity check fail (dired-file-name-at-point returns nil),
though not in the way Hydra reports (it shows point being on the ".."
entry).)
