It seems 80 columns is a good default for `split-width-threshold'.

I don't see how this would help to decide whether to split a window
vertically or horizontally, or to display a buffer in a new window.
For example:

|                |                                |
|   80 columns   |        160 columns             |
|                |                                |
|                |                                |
|                |                                |
|                |                                |

When the right window is wide enough to be split horizontally,
and point is in the left window, what is the best to do here?

1. display a buffer in the right window without splitting it;
2. split the wide right window horizontally and display a buffer
   in a new window;
3. split the left window vertically (this option is preferable
   for some buffers, e.g. for calendar)

And how to express these preferences using user options?
