Looks good.

To prevent this in the future, I switched my default --root= to point to
a symlink. I wonder if we could do something in the test suite, though,
as we did long ago by introducing "trash directory" with a space to
catch corner cases.

I guess it would be something like:

  if test_have_prereq SYMLINKS
  then
	mkdir "$TRASH_DIRECTORY.real" &&
	ln -s "$TRASH_DIRECTORY.real" "$TRASH_DIRECTORY"
  else
	mkdir "$TRASH_DIRECTORY"
  fi

but there may be some other tweaks required (e.g., for cleanup).
