Doesn't support file name diff

$ git diff --staged

It should display once and highlight the diffs

Thanks for this @stevemao, and sorry I didn't respond until now. I see that this is still a problem. It looks like delta does highlight now, but that we are still outputting the renamed line twice.

Example input is

diff --git a/src/edits.rs b/src/edit-renamed.rs
similarity index 99%
rename from src/edits.rs
rename to src/edit-renamed.rs
index 34ff14a..a92a606 100644
--- a/src/edits.rs
+++ b/src/edit-renamed.rs

And...sorry this took such a long time to fix. But it is fixed now!

(#245 was the same as this.)
