a fix for color ls with wrapped lines.

[Alexander V. Lukyanov]

Hello, bug-coreutils!

There is a problem with color ls when a background color is used and the line
wraps. It leads to complete new line erased with the background on "bce" 
terminals.
(One may argue that rxvt behaves differently, but there are many other bce 
terminals)

One fix is to clear to end-of-line after turning off the color. Here is a patch
that does it.
