Subject: bug#39353: [PATCH] Ediff fix for ediff-scroll-horizontally
Date: Fri, 31 Jan 2020 09:29:43 -0500

When ediff-scroll-horizontally interactively calls scroll-left and
scroll-right, current-prefix-arg should be used. This allows for the
case that when no args or '-' are passed to ediff-scroll-horizontally,
it will determine the default amount (half the window width or
half-again, respectively).
