Yeah, true, there is a measure of ambiguity there.  In that case I
suppose I'd prefer to just sort of "require" the dashes to signify
options, if there's a question as to what's an option and what's
not, but whatever...

Yeah, that's what I've been doing, it's just a bit tight because
right now the program already accepts fourteen options, and finding
options that make sense while keeping them down to one-letter
arguments (don't like having to have more than one letter per arg)
can get a bit challenging.  :)

Well, thanks for the confirmation!
