What did you expect to see?
Successful fetch, as with previous go versions.
It appears that I put the arguments in the wrong order in https://go.dev/cl/556358, inadventently breaking shallow git fetches. That went undiagnosed, because it fixed the symptom I was testing for (#56881) and we didn't have any tests specifically probing for shallowness of git repos in the module cache.
