I'm not sure about this yet.
On one hand: it's nice that the completion doesn't just disappear when I
hit escape because I was typing and in the flow.
On the other hand: no other inline completion provider keeps the
suggestion when leaving insert mode.
I'm going to merge this so we can get it into nightly and try it out for
the next couple of days. cc @ConradIrwin
Release Notes:
- vim: Do not dismiss inline completions when leaving insert/replace
mode with `<esc>`.
