I think the name "unchanged" is a reference to: the state recorded in this file is before all the interesting changes done in this test. So another for-each-ref, after the "lock, start a process that waits for and then removes the ref" begins but while the other process is still waiting, whose output is compared with "unchanged" may have been another way to perform this test, but we have "it could be $D that is what we want, and two plausible 'wrong' answers are $C and undefined" that is sufficient. So I agree with removing the line that creates "unchanged". The other test to the file added by the same commit 6a2a7736 (t1404: demonstrate two problems with reference transactions, 2017-09-08) creates the "unchanged" file in the same way, but it does get used after running "update-ref" that is tested. I would not be surprised if the one removed by this patch was created by a cut-and-paste by mistake.
