cmd_fetch() does the following with the assumption that objects are fetched: * Run gc * Write commit graphs (if enabled by fetch.writeCommitGraph=true) However, neither of these tasks makes sense if objects are not fetched e.g. `git fetch --negotiate-only` never fetches objects. Speed up cmd_fetch() by bailing out early if we know for certain that objects will not be fetched. cmd_fetch() can bail out early whenever objects are not fetched, but for now this only considers --negotiate-only. The same optimization does not apply to `git fetch --dry-run` because that actually fetches objects; the dry run refers to not updating refs.
