=begin
ARGF#each_char, ARGF#each_byte, ARGF#bytes, and ARGF#chars now return nil when passed a block. On 1.8 they returned self. self is preferable because:

• The documentation for IO#each_char and IO#each_byte promises that self will be returned.

• It allows method chaining.

• It's backward compatiable.
