.. method:: file.readline([size])
Read one entire line from the file. A trailing newline character is kept in the
string (but may be absent when a file ends with an incomplete line). [#]_ If
the *size* argument is present and non-negative, it is a maximum byte count
(including the trailing newline) and an incomplete line may be returned. An
empty string is returned *only* when EOF is encountered immediately.
