[Bug c/31377] New: wrap_help error

[george at houseofellery dot com]

in the file "opts.c", in the function "wrap_help", the var 'room' is calculated
as the space remaining between the the left item field width and the rightmost
column (which defaults to 80 chars). it is then compared to the columns value:

      room = columns - 3 - MAX (col_width, item_width);
      if (room > columns)
        room = 0;
      len = remaining;

I assume this is supposed to determine if the left field is taking up more than
the entire width of the line and if so, sets it to 0 as there is no room left. 
to do this, the correct code should be

      room = columns - 3 - MAX (col_width, item_width);
      if (room < 0)
        room = 0;
      len = remaining;

admitedly, since all the help lines that print out don't have a left field that
comes close to taking up the entire line, this case never occurs, so this is a
trival case.
