bug#13191: 24.3.50; insert-directory: Always replace "total" with "total used in directory"

[Christopher Schmidt]

severity: wishlist

In insert-directory there are these forms:

    (goto-char beg)
    ;; First find the line to put it on.
    (when (re-search-forward "^ *\\(total\\)" nil t)
      (let ((available (get-free-disk-space ".")))
        (when available
          ;; Replace "total" with "used", to avoid confusion.
          (replace-match "total used in directory" nil nil nil 1)
          (end-of-line)
          (insert " available " available))))))

I think "total" should always be replaced by "total used in directory"
even if Emacs is not able to get the free disk space.  This increases
consistency and avoids confusion by other packages which rely on
consistent output, such as dired-details,

Here is a patch.

If this patch is applied, tramp (tramp-sh-handle-insert-directory)
should be modified to do the same.
