What happened to the patch to add a boost::advance function designed to 
work with Boost.Iterator's concepts?

Three years ago there was a thread pointing out the problem with 
std::advance not treating random access traversal iterators as random 
access (because of the reference type).  Sebastian Redl posted a patch 
to add a boost::advance (and boost::distance) function. 
<http://lists.boost.org/Archives/boost/2007/09/127785.php>  I don't see 
any proof of this patch ever being applied.

Someone filed a bug report two years ago to bring attention to the 
patch, and it still hasn't been applied. 
<https://svn.boost.org/trac/boost/ticket/2539>

Is there a reason it hasn't been applied (the collision with the 
boost::distance supplied by Boost.Range?) or has it just fallen through 
the cracks?
