Terminal width detection
------------------------
Key: CLI-166
URL: https://issues.apache.org/jira/browse/CLI-166
Project: Commons CLI
Issue Type: New Feature
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.

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().
