For now if no flag(s) set, service update will still try to do an update as below, it should return an error instead.

$ ./kn service update hello
Waiting for service 'hello' to become ready ... OK

Hi @zhanggbj. Thanks for your PR.

I'm waiting for a knative member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

I think you can reduce a if-else depth by swapping the if-else block and using t.Fatal.

@toVersus I addressed it, thanks!

 				return err

The other option would be to do this in a PreRun function which should allow separation of the checks to the Run. See this comment from Cobra community.

Since this check is simple, it's likely OK here but if we start adding more such checks or other commands then PreRun could be a nice way to write these pre-condition code. Cheers :)

@maximilien As you mentioned, there may be more checks needed later, and people even mentioned about the odd error message when wrong args here #317, so I moved this part to PreRun. Thanks!
