It's introduced in 1bd8c8f (git-upload-pack: Support the multi_ack
protocol - 2005-10-28) but probably better documented in the commit
message of 78affc4 (Add multi_ack_detailed capability to
fetch-pack/upload-pack - 2009-10-30).

Once the 'done' line is read from the client, the server will either
send a final 'ACK obj-id' or it will send a 'NAK'. The server only sends
send a final 'ACK obj-id' or it will send a 'NAK'. 'obj-id' is the object
name of the last commit determined to be common. The server only sends
ACK after 'done' if there is at least one common base and multi_ack or
multi_ack_detailed is enabled. The server always sends NAK after 'done'
if there is no common base found.
