You have not read the C++ source of Qt4 correctly.

QTextEdit::append (see src/gui/widgets/qtextedit.cpp) calls
QTextControlPrivate::append (see src/gui/text/qtextcontrol.cpp). This
method uses a standard QTextCursor instance.

So it is not PyQt4's fault.

As far I understand QTextEdit::setTextCursor is only meant for making
selections and to position your visible cursor.

I have worked a lot with QTextEdit and I would suggest not to use
QTextEdit::append at all if you want to do some advanced stuff. If you
explain what you want to do, perhaps people could help you.
