We discussed this versus manually setting commit, but I think there are good arguments either way. We can come back to this, but will merge as fetch depth 2 is an improvement over the default fetch depth of 0. It also (indirectly and subtly) communicates to the user that fetch-depth 1 may not work for some reason.
