* src/move.c (do_next_word): Rewrite this function to use the same
logic as do_prev_word(), reducing its number of lines to half.
2015-09-05 Benno Schulenberg <bensberg@justemail.net>
* src/winio.c (display_string, edit_draw): Force a redraw of a line
only when it contains a multicolumn character, to spare all regular
