It seems the leader.fo example lacks the text-align-last="justify" property on 
the enclosing block. Because of that, FOP assumes the same alignment ("start") 
on the line containing the leader and does not extend the leader to the end 
boundary of the reference area. See the attached diff - this makes the leaders 
work fine.

FOP developers, could someone review/commit the attached diff?

Regards,
Alexey.
