I've explained the issue in that thread:

As hinted there, a solution might be to allow that the (single) argument of an "Option" (cf. "hasArg()") be split according to a user-defined regexp pattern. If given a split pattern, the code would convert a single-arg "Option" into a multiple-args one (where the arguments are the result of splitting the single-arg string with the pattern).
