Add delete forward <C-k> and backward <C-u>
Choose the readline defaults for the behavior of these two functions/keybindings. Depending on the program, either of these can delete the whole line. Note that by default in [compose], <C-k> is bound to :prev-field<Enter>. Leave it up to the user whether or not they want to rebind the key in [compose].
