Would you mind adding a cookie to the overlay in
`diff-hl-dired-highlight-items`.

    (overlay-put o 'diff-hl-dired-cookie type)

If this cookie is available, I can use it in the following ways.

1. Mark the files based on vc state.  See command
   `diff-hl-dired-mark-vc-states` and the associated screenshot `M-x
   diff-hl-dired-mark-vc-states.png`.

2. Fontify the file names based on vc state.  See command
   `diff-hl-dired-fontify` and the associated screenshot `M-x
   diff-hl-dired-fontify.png`.

   
In a sense, (1) is a GOOD---this is subjective, ofcourse---one other
way of fontifying a dired lines on vc state.

- diff-hl-dired-mode :: Put the vc state in indicator in fringe
- diff-hl-margin-mode ::  Put the vc state in margin
- diff-hl-inline-mode(?) :: Put the vc state right on the file name or
  the dired line.  


I only need the cookie, and NOT the commands that I have attached.
Bonus points if you introduce some variation of my custom command in
the library.

----------------

Backstory: Yesterday, I was cleaning up a repo which I had been
working on-and-off for the last few years.  Even though it was version
controlled, there were lots of artifacts which were never checked in.
I was apprehensive that could be some interesting titbits in the
"unknown" file.  And there were quite a good number of "unknown" files
.... and I found `M-x vc-dired` too wordy, and distracting.

----------------

Remarks, and possible areas of improvement:

1. `diff-hl-dired-mode` kicks of an async process, and I wanted some
   visual indication that the async process has finished, and I am
   seeing ALL OF the unknown files.  I would have appreciated an echo
   area message, or a mode line indicator that the process has
   finished.

2. `C-x v d` recursively lists all "unregistered" files, but
   `diff-hl-dired-mode` lists only the entries in current directory.

    I would have appreciated an option to do a recursive listing of
   files ....
