We must admit that nowadays 80x25 terminal is not enough :(

Would be cool if most of tools (netstat, systat, etc...) could
determine size of terminal and dynamically widen all their fields.
Thus, tool can run w/o any abbreviations when run in a script mode,
run abbreviated on a small terminal, and run verbose on a wide

This sounds like a generic library providing a special version
of printf(3), which specifies minimal and maximum sizes for fields
and when extra terminal width is available it distributes this
width evenly between all fields. Name it 'elastic printf'.
Sounds like a nice Google SoC project. Or might be that such
library already exists.

Totus tuus, Glebius.
