Thank you Kohei for your feedback, I pushed 2 commits, see:
https://gerrit.libreoffice.org/gitweb?p=core.git;a=commitdiff;h=8068f50276659058ef02958996d8ef84cd89017f

But there are still these:
[lingucomponent/source/languageguessing/simpleguesser.hxx:43]: (style) 
'SimpleGuesser::operator=' should return 'SimpleGuesser &'.
[reportdesign/source/filter/xml/xmlComponent.hxx:37]: (style) 
'OXMLComponent::operator=' should return 'OXMLComponent &'.
[reportdesign/source/filter/xml/xmlFunction.hxx:41]: (style) 
'OXMLFunction::operator=' should return 'OXMLFunction &'.
[reportdesign/source/filter/xml/xmlGroup.hxx:38]: (style) 
'OXMLGroup::operator=' should return 'OXMLGroup &'.
[reportdesign/source/filter/xml/xmlCell.hxx:41]: (style) 
'OXMLCell::operator=' should return 'OXMLCell &'.

All except first one, return an object instead of a ref to an object. I 
don't know if I can't just put "&" or if it should be investigated.
First one isn't an assignment but a comparison! Isn't it a little dangerous?
