Minor revisions to clarify the status of xreadlines(), change the way 

iteration support was documented; the docs for __iter__() were just
confusing.

Add a \code{'U'} to mode to open the file for input with universal newline
Add a \character{U} to mode to open the file for input with universal newline
support. Any line ending in the input file will be seen as a
\character{\textbackslash n}
in Python. Also, a file so opened gains the attribute \member{newlines};
the value for this attribute is one of \code{None} (no newline read yet),
\code{'\textbackslash r'}, \code{'\textbackslash n'},
\code{'\textbackslash r\textbackslash n'} or a tuple containing all the
newline types seen. Universal newlines are available only when reading.
