Wrong diff highlights for a lot of unchanged lines

[c02y]

Thanks for reporting a bug! Please include all of the following:

(1) A description of the issue. A screenshot is often helpful too.

(2) A copy of what you're diffing. If you're diffing files, include the before and after files. If you're using difftastic with a VCS repository (e.g. git), include the URL and commit hash.

(3) The version of difftastic you're using (see difft --version) and your operating system.

When I use difft as the diff pager in lazygit, I see that a lot of unchanged lines are highlight inside lazygit
difftastioc version: Difftastic 0.58.0 (0c9277108 2024-05-10, built with rustc 1.78.0)

When using difft as the pager in lazygit/config.yml
