Closing the commit view without writing anything causes a commit with all comments

[cfal]

Description

after opening the commit view (cc), it doesn't seem possible to exit without committing, even when the file is not saved, and no comment is written. a commit with only comments is always created:

Steps to reproduce

Minimal config

vim.cmd([[set runtimepath=$VIMRUNTIME]])
vim.cmd([[set packpath=/tmp/nvim/site]])
local package_root = "/tmp/nvim/site/pack"
local install_path = package_root .. "/packer/start/packer.nvim"
local function load_plugins()
  require("packer").startup({
    {
      "wbthomason/packer.nvim",
      {
        "TimUntersberger/neogit",
        requires = {
          { "nvim-lua/plenary.nvim" },
          { "sindrets/diffview.nvim" },
        },
        config = function()
          print("loaded neogit")
          require("neogit").setup()
        end,
      },
    },
    config = {
      package_root = package_root,
      compile_path = install_path .. "/plugin/packer_compiled.lua",
      display = { non_interactive = true },
    },
  })
end
if vim.fn.isdirectory(install_path) == 0 then
  print("Installing neogit and dependencies.")
  vim.fn.system({ "git", "clone", "--depth=1", "https://github.com/wbthomason/packer.nvim", install_path })
end
load_plugins()
require("packer").sync()

I'm not sure if this is a dupe of #320, but i haven't changed any comment character.

I've run into this exact same issue. In fact, I've also written a partial commit message, saved and closed the commit buffer, and then answered "no" to the commit prompt, and still ended up with the commit going through.
