The "debug" and "rollback" verbs appear to have been added early in the development life of git-p4. They were once used as debugging tools, but no longer serve any useful purpose either for developers or users. Removing these verbs simplifies the script by removing dead code, and increases usability by reducing complaexity.

This time, however, I think it would be much easier to give a proper analysis of what it is designed to do and what it does, to convince readers why it is too trivial to be worth having the code (compared to the PATCH 2/2).

I have never used the P4Debug subcommand for debugging git-p4, and I'm not sure what I would use it for. Removing it seems sensible. As noted by Junio, s/delete/debug/.

It is hard to make such a broad "no useful benefit" claim without giving a bit more analysis [*]. With only that single sentence, it is far worse justification than saying that "The author tells us not to use it, and it is not even documented" to convince others why removal is a good idea. I'd suggest dropping that sentence (replace it with something we can objectively verify, like "it is not even documented", if you want to). Thanks.

All my modifications in the git-p4 area stem from trying to let the CI/PR builds pass... So I don't feel that I am competent enough a reviewer for this patch series.
