[PATCH 0/2] [GSOC] cherry-pick: fix bug when used with GIT_CHERRY_PICK_HELP

This patch fixes the bug when git cherry-pick is used with environment variable GIT_CHERRY_PICK_HELP, and makes git chery-pick advice message better.

v2: https://lore.kernel.org/git/pull.1001.v2.git.1627135281887.gitgitgadget@gmail.com/

v2-->v3:

 1. Add hidden option --rebase-preserve-merges-mode to git cherry-pick.
 2. Split print_advice() into itself and
    check_need_delete_cherry_pick_head().
 3. Only allow git cherry-pick skip check_need_delete_cherry_pick_head().
 4. Use better git cherry-pick advice message.
