DEFAULT_CONTROL_D_HANDLER handles a user's Control-D (^D) presses. Add unit tests for ^D presses. Note that this commit doesn't include unit tests for the situation when ^D is being pressed in an expression[1]. [1]: Example of the untested situation: % pry [1] pry(main)> class Foo [1] pry(main)* ^D [2] pry(main)> Signed-off-by: Kyrylo Silin <kyrylosilin@gmail.com>
