(v6) Undo and [[CURSOR]]

[Tlon2010]

Not a major issue, but with a script like this:

Thanks, [[TO=firstname]].[[CURSOR]]

which returns, with the cursor after the period:

Thanks, John.

If I hit ctrl-z to undo, I get:

Thanks, John. [[CURSOR]]

Previous versions would undo the entire template. Now, the cursor variable shows up in the undo action.
