Boolean? What would be the semantics of multiple occurences? If you want
integer variable that is incremented by 1 for each occurrence, then I think
this is entirely syntax matter, and probably is best handled by taking
vector<option> returned by parse_command_line, finding all -v occurences,
and merging them into a single option, with a value equal to the number
of occurrences. There is no built-in way to do this.
