fakevim: fix undo() behaviour

This is the finalization of the change started with 3c0ca8c18881.
Fakevim undo was broken due to behavioural changes in QTextDocument
in Qt 4.6. Now that QTextDocument has gotten new accessors to the
needed (and previously available) data we can use it.
(cherry picked from commit 0bc1095b70bf698e43e5a5a74a06027aa2ece2e3)
