Literally `jj undo`

There's a whole operation log (`jj op log`), as another sequence of actions, and you can undo them. It gets crazier from there, but I've also been enjoying jujutsu lately and I had to RTFM a good couple of times to get comfortable with it.

Also cool: jujutsu remembers every previous state of all your changes. So you make some edits, run `jj status` (or anything), and keep working.

Two hours later you realize your experiment is a total failure and you wish you had the half-working changes from earlier. You don’t need to have actively commited anything, it’s all in the obsolte log and you can retrieve it.

I want to repeat that last bit. Unlike git, there was no point where you needed to finalize your changes with a commit in order for them to be persisted and archived for later retrieval.

You can even undo operations that aren't the most recent one.

Huh this comment thread may have convinced me to finally try it. I’m comfortable with git, and fixing mistakes in git, but not being able to trivially reverse any and every transaction is annoying.
