unused positional argument / value

I got no parsing error if a positional argument is present

example:
no value/positional arguments allowed at all

option with space
abc.exe -t myPath/with a/unwandted/space

so the option is myPath/with and the rest is completely lost without an error

Am I missing a special configuration here?

Start by reproducing the reported command, `abc.exe -t myPath/with a/unwandted/space`, and inspect how the parser handles the extra positional value. Done means the unused positional argument is rejected with a parsing error, or the supported configuration for rejecting it is clearly established.
