No, the point is that "git-rev-list" already does all of [1] in the core.

If you do

	git-rev-list --parents --remove-empty $REV -- $filename

then you'll get the whole history for that filename. When it ends, you 
know the file went away, and then you do basically _one_ "where the hell 
did it go" thing.

And yes, it's not git-ls-tree (unless you only want to follow pure 
renames), it's actually one "git-diff-tree -M $lastrev". Then you just 
continue with the new filename (and do another "git-rev-list" until you 
hit the next rename).
