Looking at the history I think it is fair to conclude that 
GIT_CHERRY_PICK_HELP was introduced as a way to help people writing 
scripts built on top of 'git cherry-pick' like 'git rebase' that want to 
have a custom message and do not want to leave CHERRY_PICK_HEAD around 
if there are conflicts. I don't think it was intended as a way for users 
to change the help when cherry-picking and has never been documented as 
such. I think we'd be better to focus on improving the default help that 
cherry-pick prints as the second patch in this series does.

Best Wishes

Phillip
