[PATCH] Formatting patch for psql

Hi,

Here is my patch to make psql handle multi-line output sanely. Instead
of embedded newlines splattering your output across the screen,
everything gets indented to the right column.

It basically works by extending the *_width functions to instead work
out the estimate width, height and formatting space of each cell. Then
the output goes through each cell formatting as it goes and outputting
lines at the right places.

I imagine it will be tweaked by others because everybody has different
ideas about how they want the output done. This just has the minimum
extra formatting to make the output unambiguous.

Have a nice day,
