Describe the bug

When I use the picker to search for help, I works nicely, when I open with <CR>. However, if I use <C-s> or <C-v> (default picker keys), the edit_split() and edit_vsplit() seem to behave differently (also edit_tab() is affected). I am not able to follow tags in the help using <C-]>. It turned out that the iskeyword value is not set correctly for those files. The only exception is the main help file, because it has the correct value in the modeline.

This is, how it should be

  iskeyword=!-~,^*,^|,^",192-255

This is what I get out of the value:

  iskeyword=@,48-57,_,192-255

Remark: Using the default way (:h HELPTAG) works correctly as well.

Steps To Reproduce

1. Open Snacks.picker.help() (with config just <leader>sh)
2. Use <C-v> or <C-s> to open the selected help file in a split window (still in insert mode)
3. Check with :verbose set isk

Expected Behavior

iskeyword is correctly set and following tags works.

Repro

-- vim: ts=2 sts=2 sw=2 et
vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
  spec = {
    {
      "folke/snacks.nvim",
      opts = {
        picker = {
          enabled = true,
          win = {
            -- input window
            input = {
              keys = {
                ['<C-t>'] = { 'edit_tab', mode = { 'i', 'n' } },
              },
            },
          },
        },
      },
      keys = {
        { "<leader>sh", function() Snacks.picker.help() end },
        { '<leader>sn', function() Snacks.picker.files({ cwd = vim.fn.stdpath 'config' }) end },
      },
    },
  },
})

Thanks. However this call fails on my system.

  dd("help")

Edit:
After deleting this line, vsplit and tab don't work at all.

Edit2:
tab opens in a new tab, but then applies the usual split similar when directly calling :help.

Removed. Was left-over debug.
I actually have a github action that checks for that, but it doesn't seem to work. ha

I think splitting it in 2 commands is not suitable. In case of help one would have to concat the commands somehow. Calling :vertical help snacks.nvim.txt works correctly. So adjusting function M.help(picker) in picker/action.lua:355. Is it possible to store some prefix? I am trying to dig through the code, but am still struggling..

[folke]

I don't get it. Just tested this all again and it works how it should.

It does set iskeyword correctly, yes. But both edit_split <C-s> and edit_vsplit <C-v> open it as if there is no split command in advance. And after mapping <C-t> to edit_tab (updated the config above), this is done in a new tab, but only half the window is used.

If this is currently different for you, then I am also not sure. I am running the nightly version of Neovim. Could this be an issue?
