Diff seems to contain unchanged chunks

[foresterre]

Summary

The diff seems to contain unchanged lines, as both added and removed

Expected:

Diff to be empty, or only show what changed.

Actual:

Shows all lines in file as both added and deleted.
I think this is also the case for changed files in at least this example, but it's a lot easier to spot in unchanged files.

Examples:

• https://diff.rs/cargo-msrv/0.16.0-beta.25/0.16.2/src%2Fexit_code.rs
• https://diff.rs/cargo-msrv/0.16.0-beta.25/0.16.2/src%2Fdefault_target.rs
• https://diff.rs/cargo-msrv/0.16.0-beta.25/0.16.2/.github%2Fworkflows%2Fdocker.yml
• https://diff.rs/cargo-msrv/0.16.0-beta.25/0.16.2/.github%2Fdependabot.yml
• https://diff.rs/cargo-msrv/0.16.0-beta.25/0.16.2/.dockerignore

I also checked for whitespace changes:

Hey, thanks for this bug report! I'll look into it. It might also be a bug with the similar crate that we use for generating the diff.
