A git-mv question

[Ron Garret <ron1@flownet.com>]

If I do a git-mv *and* edit the file all in one commit, does that get 
recorded in a way that allows git to track the change through the 
changed file name?  In other words, if I do just a git-mv (without 
changing the file) git can track that by observing that two differently 
named objects in two different commit trees contain the same blob.  But 
if the file is edited then the blobs will be different.  Is git smart 
enough to distinguish a git-mv and edit from, say, the equivalent git-rm 
and git-add?  If so, how does it do it?

Thanks,
