feature: Snacks.terminal gracefully handle :wqa

[tonymajestro]

Did you check the docs?

• I have read all the snacks.nvim docs

Is your feature request related to a problem? Please describe.

I often have several buffers open and when I want to exit neovim, I use :wqa. However this causes issues when the snacks terminal buffers are still open, resulting in the following errors:

E948: Job still running
E676: No matching autocommands for buftype= buffer

It would be nice if the terminal plugin was able to suppress errors related to writing to the terminal buffers when neovim is trying to exit.

Repro steps

Config:

local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
	vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
	vim.fn.system({
		"git",
		"clone",
		"--filter=blob:none",
		"--single-branch",
		"https://github.com/folke/lazy.nvim.git",
		lazypath,
	})
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
	-- do not remove the colorscheme!
	"folke/tokyonight.nvim",
	{
		"folke/snacks.nvim",
		opts = {
			terminal = {
				enabled = true,
			},
		},
	},
}
require("lazy").setup(plugins, {
	root = root .. "/plugins",
})

vim.opt.termguicolors = true
vim.cmd([[colorscheme tokyonight]])

• Open neovim with nvim -u repro.lua
• Open snacks terminal with :lua snacks.terminal.toggle()
• Hide snacks terminal with :lua snacks.terminal.toggle()
• Try to quit neovim with :wqa

Describe the solution you'd like

It would be nice if the plugin could suppress errors related to writing to the terminal buffers when exiting neovim with :wqa

Describe alternatives you've considered

I have worked around this by first doing :wa (which does not seem to trigger any errors) followed by :q. However it would be nice to be able to quit with one command using :wqa

Thanks for looking into this!

This problem was not fixed by the ExitPre fix.

This is a bug in the Neovim terminal, so I think a workaround exists, but it's difficult to solve.
