* java/io/LineNumberReader.java
(mark): Improved error checking.
(read): Likewise.
(skip): Likewise. Skip is now really eating the specified number of
characters.
* java/io/CharArrayReader.java (read): It should throw
IndexOutOfBoundsException and not ArrayIndexOutOfBoundsException (see
mauve).
* java/io/BufferedReader.java (readLine): Make readLine() really block
until either EOF is reached or a true error happens.
