title: Open two help windows in vertical splits
body: <p><a href="https://stackoverflow.com/questions/630884/opening-vim-help-in-a-vertical-split-window">Opening Vim help in a vertical split window</a> explains how to open help in a vertical split. However, suppose I run <code>help fzf</code> followed by <code>vert help vim-go</code>. Vim ignores the <code>vert</code> and just replaces the <code>fzf</code> help with <code>vim-go</code> help.</p>
  
  <p>How can I open two help subjects in side-by-side splits? </p>
