🐛 Adding an empty file doesn't show up in `git show`

[gibfahn]

If a commit adds an empty file, delta doesn't show it in the output, but git does.

I'm assuming this is a bug, but in case it's a feature, it's very helpful to show these empty files, as they often have marker or other useful purposes.

Minimal reproduction:

touch foo
git add foo
git commit -m 'Test'
git --no-pager show
GIT_PAGER=delta git show

Output:

$ GIT_PAGER=delta git show
