Non-"truncate" "sticky" mode should become the default mode

Non-"truncate" "sticky" mode should become the default mode.

After the changes are made in #35, it should be safe to make non-truncate sticky mode the default mode. The current default setting is truncate with sticky.

This will prevent missing important details when long lines are truncated. This will also make screen-resizing more feasible, as the display will automatically correct itself during a resize.

If the console width in non-truncate mode is wider than the width of the longest line, you'll be able to tell which mode you're in because in non-truncate mode, the highlighting will stop at the last character of the line (see below).

That is unlike an active truncate mode, where the highlighting goes all the way to the end of the line (see below).
