[Zope] Undo System

[Gregor]

I have a file A and a file B in Zope.  I do the following, in order:

1. Edit A

2. Edit B

3. Edit A again.

Now I can no longer Undo transaction #1, at least not until I undo #3.
Presumably Zope knows this, otherwise it couldn't tell me as much when I try
it.

So my question is this: Is it feasible to reflect (in the undo list) which
transactions do and don't depend on others?  Basically, I am thinking that
Transaction #1 might be colored red because it requires another undo first.
