Description of problem:
When less displays CJK text that is wider than the terminal,
it skips a number of the initial lines.

Version-Release number of selected component (if applicable):
less-378-11.1

How reproducible:
Every time

Steps to Reproduce:
Inside an 80x24 terminal (or narrower if necessary) run say:

% LANG=ja_JP.UTF-8 ls -lt /usr/bin | less
    
Actual results:
A number of the initial lines are skipped by less initially.

Expected results:
All the text including the initial total line should have been displayed

Additional info:
I can reproduce this in gnome-terminal, kterm, uxterm and konsole.
If the terminal is wide enough to display each of the initial lines 
then all the text from the top is displayed fine.

Press Esc-> and then Esc-< brings the very top of the text into display.
