commit fe2164949b38a7f73883dbdcb3271b94e5c81744
Author: Noel Grandin <noel.gran...@collabora.co.uk>
Date:   Tue Jan 24 13:19:04 2017 +0200

    teach unusedvariablecheck plugin about SfxPoolItem subclasses
    
    which can all be treated as SAL_WARN_UNUSED
    
    The eehtml.cxx change probably fixes some CJK/CTL bug somewhere
    
    Change-Id: I6852129540f316075aee907971ac19418d71dd9a
