[Python-Dev] Compile() and Windows/Mac newlines
In python-list thread Does Python 3.1 accept \r\n in compile()?
jmfauth notes that
compile('print(999)\r\n', 'in', 'exec')
works in 2.7 but not 3.1 (and 3.2 not checked) because 3.1 sees '\r' as
SyntaxError.
I started to respond that this is part of Py3 cleanup with newlines
converted on input and back-compatibility with ancient Python not
needed. Then I saw in 3.2 manual
Changed in version 3.2: Allowed use of Windows and Mac newlines. Also
input in 'exec' mode does not have to end in a newline anymore. Added
the optimize parameter.
I verified second statement (print(999) works) (and remember commit
for third), but original above gives same error. Should Allowed use of
Windows and Mac newlines. be deleted? What else could it mean other
than use of '\r' or '\r\n'?

After tracing the questioned comment to B.Peterson's r76232 merged from
2.7 r76230 fix several compile() issues by translating newlines in the
tokenizer, I decided to open http://bugs.python.org/issue10792
