My editor shows signs on the margins to indicate changes since last commit. I wanted it to show diffs from an arbitrary commit.

This feature request had been understandably refused a year ago: https://github.com/mhinz/vim-signify/issues/232

So I fixed it for myself, in 3 easy steps:

1. Find a simpler version: 1650 => 900 lines.
2. Delete even more code: -600 lines.
3. Add the feature: +2 lines.

The final result only works for me. I believe we should share raw VimScript, not packages.
