Iuse my custom, simple Lua module lazyloader. In that way nvim-tree isn't setup and no module is loaded before calling function defined in keymap.

It has a drawback:NvimTree* commands definitions are not loaded at that point too.

Rarely, but still, I would like to start using nvim-tree with such command.

I know that direct call torequire('nvim-tree.commands').setup() can be not recommended way, but (with this change) it allows to load command definitions without loading modules not used yet.

Thatsetup() logic could exist inplugin/nvim-tree.lua instead.
