ls: clean up after wrapped+colored file names with clear-to-EOL
This change addresses a relatively unusual case: ls --color, with
a highlighted name being printed initially in the last row of a
terminal emulator (possibly followed by other lines of output) such
that it is wrapped onto the following line, as the terminal emulator
scrolls the output. That would cause the entire following line to
