ima1zumi f589242e75 [ruby/reline] Use unix_line_discard when Ctrl-u is entered
The kill-line was called when C-u was entered, so it is now called unix-line-discard.

In readline(3):

> unix-line-discard (C-u)
>               Kill backward from point to the beginning of the line.
>               The killed text is saved on the kill-ring.
