Up till C++2011 there was no guarantee of a terminating null-pointer in std::string s.

So std::string("") is not empty empty, but it has size 0 ... and is empty()
 

Really weird :-)

The major reason why this thing was frowned upon in 2009 when I filed
an NB comment suggesting
such a change is that

if ("")

because that's just a weird case
