Jim Jagielski resolved CLI-166.
-------------------------------
Resolution: Fixed
HelpFormatter can now conditionally try to attempt to determine the terminal
width and adjust, via setAutoWidth(true). Since this is conditional, with a
failback to the default width, having this just for Unix (as it is currently)
is likely good enough.

> Key: CLI-166

> Components: Help formatter
> Reporter: Emmanuel Bourg

> Fix For: 1.3

>
> HelpFormatter could be improved by adjusting automatically its width to the
> width of the terminal. The width of the terminal can be retrieved by the stty
> command on unix systems, on Windows it requires a native call. The JLine
> project on SourceForge already implements this logic.
> http://jline.sourceforge.net
> I suggest to add a setAutoWidth(boolean) method in HelpFormatter that will
> try to get the terminal width. If it fails it'll fall back to the width
> provided by getWidth().
