patch 8.1.1773: the preview popup window may be too far to the right

commit https://github.com/vim/vim/commit/13d5c3f6162694a7e925e66fc4eea35436643384
Author: Bram Moolenaar <Bram@vim.org>
Date:   Sun Jul 28 21:42:38 2019 +0200

    patch 8.1.1773: the preview popup window may be too far to the right

    Problem:    The preview popup window may be too far to the right.
    Solution:   Keep it inside the screen.  Also keep the close button and
                scrollbar visible if possible.
