Function create_autocmd 

pub fn create_autocmd<'a, I>(
    events: I,

    opts_builder: &mut CreateAutocmdOptsBuilder,
)
where
    I: IntoIterator<Item = &'a str> + Debug + Copy,

Creates an autocommand group and associated autocommands for events.

Errors are reported to Nvim (and swallowed) so that one failing definition does not abort the rest of the setup.
