Add support for repetitions of options with integer arguments

This commit adds support for a type of command-line options that are commonly used by many GNU tools. Now with this modification if you have an option named 'verbose' with an integer argument and you enter "-vvv" as in the command line you'll get {verbose, 3} as a result.
