no, for several reasons.
(a) I don't know how to write it in coccinelle, because
(b) I have not figured out the order in which we include headers, apart from
  "cache.h goes first", the rest of the includes sometimes looks like a random
  order, because different patches add new includes at different places.
  I have the impression, that (1) some add the include after all other
  existing includes or (2) try to figure out where to add the include to make
  sense in the existing include order or (3) sort alphabetically or (4) put it
  randomly, so the chance for a merge conflict with other series in flight
  decreases.
(c) I did it in a semi automated fashion:
    while make fails:
        add another include

The mess with including repository or object-store comes from the fact that
I had v2 based on object-store, not the repository and cherry-picked this patch
over to v3. Fixed all of the includes now.

cherrypicking error, fixed.

See reply to Junio, I am not quite sure I like that.
