Now I see what you are saying.  There is code for the key all over 
"graphics.c".

And I think I see why the "set key below" always causes space removed 
irregardless of the "bmargin" setting.  It isn't conditioned the way 
"set key out" and "rmargin" is, ie for TOUT it's

    if (rmargin < 0) {
<snip>
      /* adjust for outside key */
      if (key->flag == KEY_AUTO_PLACEMENT && key->hpos == TOUT) {
          xright -= key_col_wth * key_cols;
          keybox.xl = xright + (int) (t->h_tic);
      }
<snip>
    } else

but for TUNDER, it's

    if (key->flag == KEY_AUTO_PLACEMENT) {
        if (key->vpos == TUNDER) {
<snip>
        ybot += key_entry_height * key_rows + (int) ((t->v_char) * 
(ktitl_lines + 1));
        ybot += (int)(key->height_fix * (t->v_char));
        } else {
<snip>
    }
