Dear Jeremiah,

Thank you for applying the earlier patch to the trunk. Using the trunk 
version now rather than 1.48, I ran into some other issues that I 
thought required a patch too:

https://svn.boost.org/trac/boost/ticket/6313

I hope I am right in using detail::reverse_graph_edge_property_map as a 
reversed edge wrapper around my existing edge_property_maps. For use 
with some property maps it did require me to add a default constructor 
and const reference operator[](key) const {} though.

The class reverse_graph_edge_property_map seems very useful, if not 
essential, will it remain in the detail namespace? Or are you planning a 
more generic reverse_graph_property_map (would be happy to make a patch 
for that too).

Thanks, Alex
