[vim] Yank lines

In vim, Y yanks whole line, but in CodeMirror with vim mode, Y yanks text from current cursor position to end of line (y$ in real vim).

You can reproduce it in CodeeMirror with vim mode by typing these keys: Yp. It should paste whole line, below.

I actually fixed that in 3126d9df613b03ef831ef73b31c47c967f6c4536.

I’ll just add my tuppence-worth here. I’ve been using vi and subsequently vim for 30 years, and have been using ‘Y’ all that time and find it a bit off-putting to only now have to convert to ‘yy’. I don’t use vim with any special compatibility mode. I guess I fall into the category of people who can figure out how to make it work, but what actually happened was I concluded it was broken due to a limited feature set or bug and just gave up, going back to real vim (inside crouton in this case) - as you can tell from the above link in vim.js. Anyway, up to you what you want to implement, but bear in mind some of us are using vim because we grew up on vi (I still have an original AT&T user manual somewhere, iinm), and so compatibility is of non-zero importance. I guess I have indeed learned some vim-only features, so going back to vi itself would be just as problematic. Still, this is the best implementation in javascript that I’ve seen.
