Are you sure?  I haven't tried it, but according to the
docs, -1 doesn't mean to use the original values:

   "Negative values for w and h are treated
   as offsets to the original size, e.g.
   expand=0:-50:0:0 adds a 50 pixel border
   to the bottom of the picture."

So -1:-1 would add a border of 1 pixel, which I don't
want.  But I guess expand=0:0:0:0:1 could do the right
thing (according to the example).  I'll try that the
next time I need it.  Thanks for the hint.
