Adding extra line from vim

I’m not sure how to determine if this is caused by vim or prettier, so sorry in advance if it is caused by vim.

After installing prettier globally and adding autocmd FileType javascript set formatprg=prettier\ --stdin to my .vimrc, I am seeing the following.

Initial state:

function test() {
  return 'hello';
}

Action: Type gggqG, which selects the whole file and runs prettier on it. Unfortunately, the formatting part works, but I am left with an extra newline at the end of the file. The same thing happens if you go in visual mode, select the whole file and type gq.

Let me know if there is any other info that would be helpful or if there is any way I can help. Thank you so much for your work, I have been loving prettier so far!

Thanks @lydell!

This happens because console.log() adds yet a newline at the end of file. This is not specific to vim. PR coming soon.
