diff: turn --ita-invisible-in-index on by default
Due to the implementation detail of intent-to-add entries, the current "git diff" (i.e. no treeish or --cached argument) would show the changes in the i-t-a file, but it does not mark the file as new, while "diff --cached" would mark the file as new while showing its content as empty. $ git diff | $ diff --cached --------------------------------|------------------------------- diff --git a/new b/new | diff --git a/new b/new index e69de29..5ad28e2 100644 | new file mode 100644 --- a/new | index 0000000..e69de29 +++ b/new | @@ -0,0 +1 @@ | +haha | One evidence of the current output being wrong is that, the output from "git diff" (with ita entries) cannot be applied because it assumes empty files exist before applying. Turning on --ita-invisible-in-index [1] [2] would fix this.
