Warning in GuiBox.cpp

Hi Uwe,

It seem that there is another parenthesing problem. I won't touch it 
because I do not know what the intended logic is.

  CXX    GuiBox.o
../../../../master/src/frontends/qt4/GuiBox.cpp: In member function 
‘virtual bool lyx::frontend::GuiBox::checkWidgets(bool) const’:
../../../../master/src/frontends/qt4/GuiBox.cpp:443:31: attention : 
suggest parentheses around ‘&&’ within ‘||’ [-Wparentheses]
