Description Antonio Gomes 2010-04-19 08:25:10 PDT 
In updateFocusCandidateIfCloser  method (see WebCore/page/FocusController.cpp), we do all bail out checks in the begining of the method body. If after those bail out checks, no "best FocusCandidate" has been taken yet (i.e. focusCandidate.isNull() == true) , we can safely take the current candidate, and exit earlier.

no behavior change, it is just a safe assignment shortcut.
