[KVonGit]

If you take one turn, then UNDO twice, all is well.

You are in a Room.
You can see a frob.
You can go north.

> take frob
You pick it up.

> undo
Undo: take frob

> undo
Nothing to undo!

> undo
Nothing to undo!

...but, if you take two turns, then UNDO thrice:

You are in a Room.
You can see a frob.
You can go north.

> take frob
You pick it up.

> north

You are in a Second Room.
You can go south.

> undo
Undo: north

> undo
Undo: take frob

> undo
Undo: take frob
