Missing [git diff] data when [Context lines] is small

[Nazgand]

2 pictures: Same repository, same commit, same file

[Context lines] = 3: Missing [git diff] data after line [41⇾52]

[Context lines] = 93: [git diff] data near line [149⇾291] is suddenly visible

SHA256 repository (Work in progress, relevant commit not pushed to CodeBerg and GitLab yet, thus Dropbox link to an archive)

Thanks for supporting SHA256 Git repositories; I anticipate greatness for Gittyup.

Edit:

• The version is [Gittyup v2.0.0].
• I noticed that after I added an unsigned commit, (at least some and maybe all) of the missing diff data reappeared even with [Context lines] = 3. I checked the [.tar.lzma] archive, and the diff is still incorrectly showing in the archived repository.
• I am using [NixOS 26.05 (Yarara) x86_64].
