Bugfix: Console parameter processing should handle unknown parameters with -/+ as regular parameters.

If the parameters are not found, then they should be added to the "remaining" set.
This allows unknown parameters to be used as regular parameters.

This is easily seen when using status_code or fss_status_code and attempting to pass a negative number, such as -200.
While -200 should be an out of range error for these programs, it is instead silently ignored.
Given that there is no reserved parameter with -200, then the -200 can be used normally.

There should also be a way to explicitly designate that all remaining parameters are processed as "remaining".
Add a comment by this.
There may also need to be a way to escape these parameters as an alternative.
Such changes are left to another time.
