Add psql TODO item:

> 	o Add option to wrap column values at whitespace boundaries,
>           rather than chopping them at a fixed width.
> 	  Currently, "wrapped" format chops values into fixed
> 	  widths.  Perhaps the word wrapping could use the same
> 	  algorithm documented in the W3C specification.
