Subject:    move detection doesnt take filename into account

if you move two identical {e.g.: empty} files to two new locations in a 
single commit, the move detection picks them {seemingly?} arbitrarily. 
it should use a statistical algorithm to compare the filenames and pick 
a likely match.

my apologies in advance if this isnt the right venue or is improperly 
formatted, or if this is extraneous noise, or widely known, etc.
