That seems like a bit of a dangerous "feature" to introduce with no 
warning, if that's what's really happening; what if you have a complex 
multi-edit sequence to go through when rebuilding a route-map?

I'm not seeing the behaviour - a quick test on an eBGP peer locally 
doesn't do this on our SXI4a box. Can you show some BGP config?
