> If there is not enough space to display a word on a single line,
> HelpFormatter goes into a infinite loops until the JVM crashes with an
> OutOfMemoryError.
> Test case:
> {code}
> Options options = new Options();
> options.addOption("h", "help", false, "This is a looooong description");
> HelpFormatter formatter = new HelpFormatter();
> formatter.setWidth(20);
> formatter.printHelp("app", options); // hang & crash
> {code}
> An helpful exception indicating the insufficient width would be more
> appropriate than an OutOfMemoryError.
