plain text, they correct alignment problems when rendered inside Vim
itself as a help document (where some of the markup characters become
invisible).

       The maximum number of files that will be considered when scanning the
       current directory. Upon reaching this number scanning stops. This
       limit applies only to file listings and is ignored for buffer
       listings.

       The maximum height in lines the match window is allowed to expand to.
       If set to 0, the window will occupy as much of the available space as
       needed to show matching entries.
