[issue39132] Adding funcitonality to determine if a constant string node is triple quoted

[Serhiy Storchaka]

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:

It is impossible because of using newline escaping and string literal concatenation. In the following examples 
lineno != end_lineno, but strings use single quotes:

    print('Hello '
          'world!')

    print('Hello\
 world!')

Triple quotes can be also used for strings which occupy a single line of code and do not contain \n:

    print("""exec("print('Hi!')")""")

We cannot also distinguish 1234 from 0x4_d2 and 1234.0 from 1.234e3 at the AST level.
