Operating system/version

EndeavourOS Linux x86_64 (6.1.11-arch1-1)

Describe the bug

When using empty string as mappings entry in 'mini.surround', this error is shown:

Failed to setup handlers for mini.surround

vim/keymap.lua:0: Invalid (empty) LHS

# stacktrace:
  - vim/keymap.lua:0 _in_ **set**

Any mappings entry in any 'mini.nvim' module (except 'mini.pairs') can be an empty string with meaning to not create that particular mapping. Relevant modules for LazyVim are 'mini.ai', 'mini.comment', 'mini.indentscope', 'mini.surround'.

Steps To Reproduce

1. Configure 'mini.surround' using, for example, this setup:

return {
  "echasnovski/mini.surround",
  opts = {
    mappings = {
      add = "ys",
      delete = "ds",
      find = "yf",
      find_left = "yF",
      highlight = "vs",
      replace = "cs",
      update_n_lines = "",
    },
    search_method = "cover_or_next",
  },
  config = function(_, opts)
    require("mini.surround").setup(opts)
  end,
}

2. Open Neovim.

Expected Behavior

Empty string in mappings entry doesn't result into error.
