[issue8260] When I use codecs.open(...) and f.readline() follow up by f.read() return bad result

Hi Stephane,

I think you're seeing different buffering behavior, which I suspect is correct according to docs.

codecs.open should default to line buffering[1], while open uses the system default[2].

The read() where the assert fails is returning the remaining buffer from the readline (which read 72 chars).

Asserting e.g. "f.read(1024) == ..." will give you the expected result.
