Description

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:

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

An helpful exception indicating the insufficient width would be more appropriate than an OutOfMemoryError.
