I had no idea.

Matlab is apparently placing the points like this:

	       o---o
	       |   |
       o---o   |   |
       |   |   |   |
       |   |   |   |   o---o
       |   |   |   |   |   |
     o-o   o-o-o   o-o-o   X

where an `o' represents a single point and an `X' represents a
duplicate point.

This seems very odd to me and probably not worth duplicating exactly.

Of course, if someone wants to modify Octave's current version of bar()
and put it up on the contrib ftp site, they are welcome to do so.
