Neovim version (nvim -v)

0.9.2

Operating system/version

Arch Linux

Describe the bug

I don't know if it's actually a bug or just a strange behavior, but when I set prompt_save_on_select_new_entry = false any new file is created as a directory.

Steps To Reproduce

1. Set oil prompt_save_on_select_new_entry to false
2. Open Neovim in a empty directory (for a minimal example)
3. :e .
4. Write in the oil buffer file1 switch back to Normal mode and hit Enter (to call actions.select in file1)

After these steps a new oil buffer is opened using file1 as the new directory.

Expected Behavior

I would expect it to create as a new file since oil by default creates a new file when using any name not ending in / (e.g. file1) and a new dir when using a name ending in / (e.g. dir1/).

Directory structure

Repro

-- save as repro.lua
-- run with nvim -u repro.lua
-- DO NOT change the paths
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "runtime", "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 = {
  "stevearc/oil.nvim",
  opts = {
    prompt_save_on_select_new_entry = false,
  }
}

require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here

Did you check the bug with a clean config?

• I have confirmed that the bug reproduces with nvim -u repro.lua using the repro.lua file above.
