FWIW Although I still believe that allowing text on the same line with opening or 
closing """ (except for the single-line case) is over-complicating of the model and 
adding unnecessary point of confusion, especially for the reader of code("will new 
line be inserted here?!well.. for this special case I have to check docs"..), I can 
give +1 for this updated proposal as it provides correct(from my point of view) 
behavior for "normal" multi-line string like

line 1
line 2

-> "line 1\nline 2\n"
