Correct some bitrot; some things have become inaccurate in the tutorial. 

<file>.readlines() does not call <file>.readline() internally anymore,
and the sizehint parameter should be mentioned briefly.

Some displays of floating point numbers needed to be updated due to the
change in the repr() of floats (from 1.6).

Both issues were noted by Aahz <aahz@panix.com>.

a list containing all the lines of data in the file. in the file. If given an optional parameter \var{sizehint}, it reads
that many bytes from the file and enough more to complete a line, and
returns the lines from that. This is often used to allow efficient
reading of a large file by lines, but without having to load the
entire file in memory. Only complete lines will be returned.
