nope -- if you open a file in text mode (without the "b"), the I/O layer
will translate "\r\n" to "\n" on Windows.
if you want even more robust behaviour, use the "U" flag (for universal
newlines); that'll handle old-style Mac files too.
(as others have pointed out, a plain rstrip() is usually the best choice
anyway. giving meaning to trailing whitespace in text files is usually
a really lousy idea).
