I believe this is wrong in two ways - first, it hasn't been updated
to cater for the recent "Universal Newline" support, and second, it
applies only to Python source code files (embedded code using the C
APIs should pass code using C newline conventions, ie \n characters,
as we have confirmed). I've submitted a Python bug report (SF ref
1167922) against the documentation.

I've suggested updated wording for this section as follows:

"""
A physical line is a sequence of characters terminated by an end-of-line
sequence. In source files, any of the standard platform line
termination sequences can be used - the \UNIX form using \ASCII{} LF
(linefeed), the Windows form using the \ASCII{} sequence CR LF (return
followed by linefeed), or the Macintosh form using the \ASCII{} CR
(return) character. All of these forms can be used equally, regardless
of platform.

When embedding Python, source code strings should be passed to Python
APIs using the standard C conventions for newline characters (the
\code{\e n} character, representing \ASCII{} LF, is the line
terminator).
"""

Is that clearer?
