But what about the undo information?

With QTextDocument, each document has its own undo
stack (which is what you want for a multi-document editor)
but when I setText() on the QsciScintilla the undo information
is lost.

Is there a way to save the undo stack? The only undo-related
methods I see are undo() and begin- and end- UndoAction()
