Lazygit Bug Reproduction

Issue Description

This repository is used to reproduce a bug in Lazygit related to the custom patch application feature.

Steps to Reproduce

1. Clone this repository:

   git clone https://github.com/black-desk/lazygit-bug-report-2025-04-29
   cd lazygit-bug-report-2025-04-29

2. Build a custom patch from changes to the test.md file in HEAD^.

3. Move the patch to a new commit.

Expected Result: The patch should be applied successfully.

Actual Result: Git fails to apply the patch.

Issue Verification

Here's a simple example to verify the issue in another way:

# Create a patch with zero context lines
git format-patch HEAD^ -U0

# Try to apply the patch in reverse
git apply --reverse *.patch

This will clearly demonstrate the patch application failure.
