Wrong location using the git_diff picker

[MartinDelille]

When using the git_diff picker, I have an issue with the location when selecting a diff. It goes 3 lines before the actual diff. I suspect this correspond to the hunk location which is generally 3 lines before the diff. Can I fix this by config ?

Not technically a bug: displayed diff context lines affect hunk header offsets (try git diff -U0):

Snacks.picker.git_diff({
  transform = function(item)
    if item.block and not vim.tbl_isempty(item.block.hunks) then
      local ctx_offset = 0
      local first_diff = item.block.hunks[1].diff
      for i, line in ipairs(first_diff) do
        if line:match("^%+") then
          ctx_offset = i - 2
          break
        elseif line:match("^%-") then
          ctx_offset = i - 3
          break
        end
      end
      ctx_offset = math.max(0, ctx_offset)
      item.pos[1] = item.pos[1] + ctx_offset
    end
    return item
  end,
})
