I just played around with Eagle a bit and realized the above was a stupid
statement.  The autorouter isn't smart enough to swap swappable gates or
pins.  This is meant for the human doing the layout.  Oh well, better than
nothing.  Most of the time when you have separate nets that are supposed
to be connected at at single point, you care where that point is
physically anyway.

I played around with netshort devices, and two abutting SMD pads seemed to
work best.  As I thought, everything I tried was flagged by the DRC, but
two abutting SMDs cause only a single complaint.  They should turn into
one simple copper rectangle in the end with minimum wasted space.  The
attached file is the Eagle library I created.  I've left a clear path for
adding shorts of different widths.  I did try this in a schematic and a
board, and everything seemed to work.  For whatever it's worth...
