Style issue (missing space).

Haven't checked the code, but why -g? And do we actually need a short option for this? Seems to me like a debugging feature.

I did not have a specific reason for -g other than it being available. I considered the following which made more sense, but were unavailable -s, -S, -t, -T.
I am okay with it being only available as a long option. My main purpose for this is to be able to determine the difference in error counts during a test run, as currently it is a running total at then end and it is not clear if the counters were incremented during the test case, or a previous one.

I think we should go in the similar way to --stats (AFAIU it exists only as long option).

Wonder if there is a better place so we can group options that are semantically bound to each other.

Yes, this makes sense it could be moved below or above the --stats option.
