Describe the issue

When staging/committing only selected lines from a file, the generated result can lose line breaks or merge adjacent lines. The preview and the final committed content can differ from the expected output.

Steps to reproduce

1. Open a file with multiple lines in GitButler.
2. Select only a subset of lines to stage/commit.
3. Create the commit.
4. Check the commit preview or the resulting file content.
5. Observe that line breaks are missing or lines are shifted/merged.

Expected behavior

The selected lines should be committed without altering line separation or adjacent content. Expected:

4
5
6
8
9

Actual behavior

The staged/committed result can drop newline boundaries and produce malformed content. bad result:

4
5
68
9
