When was Git changed in some kind of TSA agent one has to bribe to get
allowed to cross^Wcommit ? Why git lawyer is not implemented ? I want a
fair trial !

And before adding to Git a perfect lie detector (how will it able to
make the difference between truth and lie ? then, will it be able to
make the difference between good and bad ?, oh god, no !), I would
prefer to have it detect bugs before one could commit instead.

You seems to think I'm lying, but I'm not a liar: I just need to make
some arrangements with the history under another identity, as I could be
legally bound to. So it may sound like a lie for you, but ultimately,
it's the plain truth.

So as the tool is not in position to distinguish lie from truth, I'd
prefer to not see this concept brought here.

Thanks for reminding this: I have to use GIT_COMMITER_DATE,
GIT_COMMITER_NAME and GIT_COMMITER_EMAIL.

As I'm not calling for adding --date and --author, I will continue to
use the environment variables: they're good enough for the job.

Regards.
