I disagree that U makes no sense for binary file reading.

In python 3:

'b' means, "return byte objects"
't' means "return decoded strings"

'U' means two things:

1) When iterating by line, split lines at any of '\r', '\r\n', '\n'
2) When returning lines split this way, convert '\r' and '\r\n' to '\n'

If you support returning lines from a binary file (which python 3
does), then I think 'U' is a sensible thing to allow - as in this
case.

Best,

Matthew
