Add `autocmd` to automatically expand the `_template` snippet on the `BufNewFile` event, if the expansion fails because the `_template` snippet does not exist for the current `filetype` undo the changes. Do the same thing when the `filetype` changes to `help`, since these are `text` files to begin with the first `autocmd` has no effect.
