Adds a `name` key to the opts dict passed to Lua command callbacks created using `nvim_create_user_command()`. This is useful for when multiple commands use the same callback. Note that this kind of behavior is not as strange as one might think, even some internal Neovim commands reuse the same internal C function, differing their behavior by checking the command name. `substitute`, `smagic` and `snomagic` are examples of that. This will also be useful for generalized Lua command preview functions that can preview a wide range of commands, in which case knowing the command name is necessary for the preview function to actually be able to execute the command that it's supposed to preview.
