I have struggled for a day and a night trying to make preview (pager) wrap long 
lines.  From "Dependencies" section under http://nongnu.org/ranger, I got an 
impression that Ranger uses "less" for pager - "A pager (<a>less</a> by 
default)", but having changed the following lines inside 
$HOME/.config/ranger/apps.py to add an "N" after "R", which will make "less" 
display line number, has made no difference.
def app_pager(self, c):
  return 'less', '-R', c

By looking around codes under /usr/share/pyshared/ranger/, I guess Ranger 
default uses an embedded pager.  So my question is how I can turn on wrap 
inside this default pager.

There are two screenshots on Ranger's main websites, one shows wrap-enabled, 
one doesn't.

I am using Ubuntu 12.04, and Ranger version is "ranger 1.5.2 (stable)".  Thank 
everyone for this great product.
