Stick line length to what is actually used (removing an optimization that
allowed it to be bigger), and use clear line/EOL sequences rather than spaces
in copy/scroll mode.
This fixes xterm copy/paste from tmux which treats trailing spaces differently
from clearing a line with the escape sequences. Reported by martynas@.
