I think it's working as intended, because GIT_CONFIG is only supposed
to affect 'git config' and is only documented in the git-config(1) man
page.  Perhaps the wording could be improved to be more explicit about
this.

Note that more general environment variables affecting more git
commands are documented in git(1), and GIT_CONFIG is not mentioned
there.

Try setting and exporting the environment variables GIT_AUTHOR_NAME,
GIT_AUTHOR_EMAIL, GIT_COMMITTER_NAME, and GIT_COMMITTER_EMAIL instead.
