That's true, or at least "off-by-one" different than recent ZODB 3.2s.
 Rev 30334 fixed two bugs in the implementation, so that the behavior
matched what the documentation has always said undoInfo() did.  I
don't know when the implementation got out of synch with the docs, but
however people want to resolve this I will not leave the
implementation disagreeing with the docs.

I added details there.
