hello,
git-diff-tree without --root is absolutely silent for the root commit,
and i see no bad effects of --root on non-root commits. are there any
hidden gotchas? IOW, why is the --root behavior not the default?
cram[1] testcase::
$ git init -q scratch
$ cd scratch
$ echo '.*.sw?' > .gitignore
$ git add .gitignore
$ git commit -q -m init .gitignore
$ git diff-tree HEAD
$ git diff-tree --root HEAD
