Re: [PATCH] t/t5534: do not unset GIT_COMMITTER_EMAIL for other tests

> Unsetting the varibale for good can have unwanted effects for new
> tests added in the future It also meant we needed to hardcode the
> value for "user.signingkey".
> Move the unset into a subshell, get rid of the hardcoded
> "committer@example.com", and switch the GPG variant to using
> test_config just like GPGSM.
