 You can close a stream using these methods:
 
-- +#close+ - closes the stream for both reading and writing.
-
-- +#close_read+ (not available in \ARGF) - closes the stream for reading.
-
-- +#close_write+ (not available in \ARGF) - closes the stream for writing.
+- IO#close: Closes the stream for both reading and writing.
+- IO#close_read (not available in \ARGF): Closes the stream for reading.
+- IO#close_write (not available in \ARGF): Closes the stream for writing.
 
 You can query whether a stream is closed using these methods:
 
-- +#closed?+ - returns whether the stream is closed.
+- IO#closed?: Returns whether the stream is closed.
 
 === Stream End-of-File
 
 You can query whether a stream is at end-of-file using this method:
 
-- +#eof?+ (also aliased as +#eof+) -
-  returns whether the stream is at end-of-file.
-
+- IO#eof? (also aliased as +#eof+):
+  Returns whether the stream is at end-of-file.
