Improve formatting of stream operators.
If there are string literals on either side of a '<<', chances are
high that they represent logically separate concepts. Otherwise,
the author could just have just a single literal (possible split
over multiple lines).
So, we can now nicely format things like:
cout << "somepacket = {\n"
<< " val a = " << ValueA << "\n"
<< " val b = " << ValueB << "\n"
<< "}";
