title: Vim: keep location list window open after selecting a file
body: <p>I need exactly the opposite behavior of <a href="https://stackoverflow.com/questions/10846598/close-location-list-when-selecting-file">this question</a>. My observation is that upon pressing <code>enter</code> on a line in location list window, the window will be closed and the main window will display the content of the selected file. As a contrary, quickfix window doesn't have this behavior, i.e., it remains opened after the selection.</p>
  
  <p>I have checked my autocmd and there is no special handling for location list or quickfix list.</p>
  
  <p>An example - <code>:lgrep hi *</code> to populate the location list. <code>lopen</code> to open the location list window. Press <code>enter</code> on any line.</p>
