Replying here instead of to Jun Hao message (I'm not subscribed to the

According to the original commit, the change to GIT_EDITOR is only
here for hooks:
commit 406400ce4f69e79b544dd3539a71b85d99331820
Author: Paolo Bonzini <bonz...@gnu.org>

git-commit: set GIT_EDITOR=: if editor will not be launched
This is a preparatory patch that provides a simple way for the future
prepare-commit-msg hook to discover if the editor will be launched.
Signed-off-by: Junio C Hamano <gits...@pobox.com>
So there is really no reason to set it earlier, and not just in the
hook subprocess environment.
Regarding dry run: the bug is present, and my patch fix it too (but is
missing a test for this).
As to which patch is better: it's really not for me to decide! It's a
question for the maintainer(s), Jun Hao patch is sure much smaller and
simpler, mine is more involved and I believe cleaner in the long term:
there is no risk of another part of the commit process to be impacted
by the change of environment. Also note that my patch changes the
merge builtin too: GIT_EDITOR will not be overriden if an editor will
be launched (when used with --edit).
