Re: [PATCH v2] [GSOC] cherry-pick: fix bug when used with GIT_CHERRY_PICK_HELP

This will break git-rebase--preserve-merges.sh which uses
GIT_CHERRY_PICK_HELP to set the help and ensure CHERRY_PICK_HEAD is

Ahh, I didn't realize we still had scripted rebase backends that
called cherry-pick as an executable.  I was hoping that all rebase
backends by now would be calling into the cherry-pick machinery
directly, bypassing cmd_cherry_pick(), and that was why I suggested
to catch stray one the end-users set manually in the environment
and clear it there.

I'm a bit confused as to what the
problem is - how is 'git cherry-pick' being run with
GIT_CHERRY_PICK_HELP set in the environment outside of a rebase (your
explanation in [1] does not mention how GIT_CHERRY_PICK_HELP is set)?

I didn't press for the information too hard, but I guessed that it
was perhaps because somebody like stackoverflow suggested to set a
message in their environment to get a "better message."
