No, sorry for my lame wording.
In the test I submitted, printing to stdout with
"print(1, file=sys.stdout);print(2, file=sys.stdout)"
outputs
"1\r\n2\r\n"
but printing to stderr with
"print(1, file=sys.stderr);print(2, file=sys.stderr)"
outputs
"1\r\n2" <- no '\r\n' at the end
I wondered why, but this is not specific to Python 3.
With Python 2.7
print >>sys.stderr, 1
doesn't output '\r\n' at the end also. So I think this may
not be a bug.
