This would flag double includes that are there for good encapsulation, 
like when a header contains an inline function definition using 
rtl::OUString (so header #inlcude "rtl/ustring.hxx"), and that header is 
included in a cxx that also contains a function definition using 
rtl::OUString (so cxx too #include "rtl/ustring.hxx").

Cool, thanks for the pointer.  Always thought about doing something like 
this, but never came around...
