    logging: really fix double blank lines in --show* output
    
    (hopefully)
    
    Changes:
       whack_comment(whackfd, " "); /* spacer */
    to:
       show_separator(s);
    which tracks if/when the spacer is really needed.  This means all
    the show code can trust that:
       show_foo():
         show_separator(s);
         show_comment(s, "Foo ...");
         show_separator(s);
       show_bar():
         show_separator(s);
         show_comment(s, "Bar ...");
         show_separator(s);
    will to do the right thing (i.e., only once blank betwen the two headings).
    
    Note that it doesn't touch the --list* functions (although it probably
    should) because there's big mobs of convoluted code between the
    list_*() calls and the show_*() calls.

    logging: add show_separator(), use to avoid double blank lines in output
    
    For instance:
    
       s = new_show(whackfd)
    
       show_separator(s);
       show_comment(s, "heading 1");
       show_separator(s);
       show_comment(s, "body 1");
    
       show_separator(s);
       show_comment(s, "heading 2");
       show_separator(s);
    
       show_separator(s);
       show_separator(s);
    
       free_show(s);
    
    Outputs:
    
       Heading 1
       <blank>
       body 1
       <blank>
       Heading 2
       <blank>
