The m_savedData member is set on two occasions: Once directly after reading the same file that is going to be written, and once directly after a successful file save. In neither case do we have to write it out again. Fixes: QTCREATORBUG-25921 Change-Id: Ie369e280f4189aefb6b2ad291426ee9e6f1ed16d Reviewed-by: Eike Ziller <eike.ziller@qt.io>
