Full diff having issues with slightly offset lines

[hhoeflin]

I have been using the plugin for a little while and really like it. However in full_diff mode, there are issues with slightly offset lines. The actual lines mentioned in the copilot-chat itself are correct

Here for example, the chat itself states

[file:src/kanbanmark/tags.py](src/kanbanmark/tags.py) line:170-170

```python
def process_list_item(event_it: peekable[tuple[Event, Range]], depth: int = 0) -> ListItemBlock:
```

and is at the correct line, but the diff shows up at line 171.

When applying the patches separately, they are applied to the correct line.

Deleted my prior comment as inaccurate. I'm unsure if this is related to the model choice, but I can say I experience this intermittently with mostly default settings:

    {
      "CopilotC-Nvim/CopilotChat.nvim",
      dependencies = {
        { "zbirenbaum/copilot.lua" },
        { "nvim-lua/plenary.nvim", branch = "master" },
      },
      cmd = { "CopilotChat", "CopilotChatOpen" },
      event = "InsertEnter",
      opts = {
        chat_autocomplete = true,
        window = {
          width = 0.4,
        },
        selection = function(source)
          local select = require("CopilotChat.select")
          return select.visual(source) or select.buffer(source)
        end,
      },
      keys = {
        { "<leader>ll", "<cmd>CopilotChatOpen<CR>", "n" },
        { "<leader>ll", "<cmd>CopilotChatOpen<CR>", "v" },
      },
    },

@jellydn This is not an enhancement, it's a bug. I am finding that I don't see it much or at all with rust code, but with python code it happens all the time. Perhaps the curly braces help clarify the code boundaries.
