    Given a list of tuples as returned by extract_tb() or
    extract_stack(), return a list of strings ready for printing.
    Each string in the resulting list corresponds to the item with the
    same index in the argument list.  Each string ends in a newline;
    the strings may contain internal newlines as well, for those items
    whose source text line is not None.

    This is useful for alternate formatting of stack traces.  If
    'limit' is omitted or None, all entries are extracted.  A
    pre-processed stack trace entry is a quadruple (filename, line
    number, function name, text) representing the information that is
    usually printed for a stack trace.  The text is a string with
    leading and trailing whitespace stripped; if the source is not
    available it is None.

    This differs from print_tb() in the following ways: (1) if
    traceback is not None, it prints a header "Traceback (most recent
    call last):"; (2) it prints the exception type and value after the
    stack trace; (3) if type is SyntaxError and value has the
    appropriate format, it prints the line where the syntax error
    occurred with a caret on the next line indicating the approximate
    position of the error.

    The arguments are the exception type and value such as given by
    sys.last_type and sys.last_value. The return value is a list of
    strings, each ending in a newline.

    Normally, the list contains a single string; however, for
    SyntaxError exceptions, it contains several lines that (when
    printed) display detailed information about where the syntax
    error occurred.

    The message indicating which exception occurred is always the last
    string in the list.
