 === The Input Stream
 
 The input stream is an +IO+-like object which contains the raw HTTP request data. When applicable, its external encoding must be <tt>ASCII-8BIT</tt> and it must be opened in binary mode. The input stream must respond to +gets+, +each+, and +read+:
-* +gets+ must be called without arguments and return a +String+, or +nil+ on <tt>EOF</tt>.
+* +gets+ must be called without arguments and return a +String+, or +nil+ on EOF (end-of-file).
 * +read+ behaves like <tt>IO#read</tt>. Its signature is <tt>read([length, [buffer]])</tt>.
   * If given, +length+ must be a non-negative Integer (>= 0) or +nil+, and +buffer+ must be a +String+ and may not be +nil+.
   * If +length+ is given and not +nil+, then this method reads at most +length+ bytes from the input stream.
