Sorry for late answer byt I was off line a few days.

Thanks, It will be great.

I have impemented a tree viewer for qgit. Tree view is updated when user browses through revisions. Loading the file names of a given tree, altough only for the open directories, is an expensive operation. So I check for different files anytime the user select a new revision and the tree viewer is open, I use this test to skip tree reloading if trees have the same files.

I have made some speed test with git-diff-tree -r --name-status --diff-filter=AD sha1 sha2

  Marco
