Why does IO#read at the end of file without argument return "", but with a
interer return nil?

---------------------------------------------------------------- IO#read
     ios.read([integer [, buffer]])    =3D> string, buffer, or nil
------------------------------------------------------------------------
     Reads at most _integer_ bytes from the I/O stream, or to the end of
     file if _integer_ is omitted or is +nil+. If the optional _buffer_
     argument is present, it must reference a String, which will receive
     the data. Returns +nil+ if called at end of file.

Is it bug?

If Beethoven's Seventh Symphony is not by some means abridged, it will soon
fall into disuse.
