[issue1677872] Efficient reverse line iterator

[Guido van Rossum]

Guido van Rossum added the comment:

I'd like to see the doc patches separated out and applied to 2.6 --
they'll automatically merge into 3.0 then. Make that a separate bug please.

I like the idea, haven't had time to carefully review the code, but
noticed one oddity:

>>> for line in reversed(open("/etc/passwd")): print(line, end="")

immediately raises

ValueError: I/O operation on closed file
