Same comment as [1/2].  Perhaps

    push: mark forced no-op pushes differently in the report

or something?

This code is in an if/else cascade of this shape:

	if we are deleting
		print [deleted]
	else if they did not have any
		print [new]
	else {
		if we forced
		then
			prepare to say forced
		else
			prepare to say an unforced update
		say "updated" in a certain way
	}

The above addition looks somewhat out of place.  I would understand
if the addition happened like so instead:

diff --git i/transport.c w/transport.c
index df518ead70..bacef94b33 100644
--- i/transport.c
+++ w/transport.c
@@ -666,6 +666,8 @@ static void print_ok_ref_status(struct ref *ref,
 			strbuf_addstr(&quickref, "...");
 			type = '+';
 			msg = "forced update";
+		} else if (oideq(old_oid, new_oid)) {
+			... prepare to say "same but forced no-op" ...
 		} else {
 			strbuf_addstr(&quickref, "..");
 			type = ' ';

to make the new logic flow more like so:

		if we forced
		then
			prepare to say forced
		else if we were forced to tell no-op push
			prepare to say we did no-op
		else
			prepare to say an unforced update
		say "updated" in a certain way
