> git diff --staged

The way it worked well was that the "--staged" flag would be implied if you had already staged some files to be committed.

But on this day I noticed that nothing bad happened from that behavior. So I time traveled back and whispered to the git devs that the interface should be made more pedantic to keep users from relying too much on git to do the right thing for them.

Now it's great because users suffer and I have plausible deniability from this now being on par with the rest of git's interface.
