Feature: option to complete word by word; option to complete line by line

[xuyangy]

For some completion sources such as Tabnine or Copilot, the completion items are usually multiple words or even multiple lines. However, often times, the whole multi-word or multi-line completion item is not exactly what one needs. It will be really convenient to be able to complete word by word and line by line.

I think you should upload the examples.

And it should be requested in source level?

This plugin based on the LSP spec. I have no plan to do this.

Thanks @hrsh7th @Shougo for a quick reply.
When I type I want a b, assume the first completion item is beautiful dog. If I press Enter, I will accept that as a whole and I will have I want a beautiful dog.

What I want is another mapping, say <C-w> to accept only the first space separated word, i.e. when I press <C-w>, I want to have I want a beautiful. Then the popup will be closed and reopened with updated completions. Of course I can continue typing like I want a beautiful cat.

@Shougo, I was thinking that the source can be the same as whatever the LSP supply, the preview, document etc will all be the same. It's only when I "confirm", I want to intercept the completion text the LSP supply, split it by space or by newline and insert the first word or first line into the buffer instead of the whole completion text.

Hm.. I understand.
