I have not tested it, but at least for normal files - and possibly also 
for sockets*, I would like under Unix to have "\r\n" and "\n" be read as 
single EOR marker. I do not want to have "\r\n" as two new lines. 
(Similarly, I also would like to read Unix "\n" files correctly on 
Winows.)  I think the current code (without patch) and the submitted 
patch handle this correctly, though I have not extensively tested it.

(I do not care about "\r" as end of line marker as it effectively plays 
no role [1].)
