在fossil-scm我有2个分支，并且已经选择了要在合并中提交的提交：
fossil merge --cherrypick chg01
如何在branch1上发现哪个提交已经在branch2上合并？实际上我需要知道哪些提交没有合并，以便我可以在必要时合并它们。
在git中，这个命令可以做到这一点：
#view diffs between branches
git log --graph --left-right --cherry-pick --oneline branch1...branch2
在下面的示例中，我希望知道 rfc-02 未应用于测试分支。
# ----------------------------------
# Create the repo and branches

fossil new main.fossil
fossil ui main.fossil &
mkdir developer
cd developer
fossil clone ../main.fossil local.fossil
fossil open local.fossil
fossil branch new testing trunk
fossil branch new production testing
#
# ..[add some files]

fossil addremove
fossil ci -m "rfc-01 ticket [12345678]" --tag rfc-01
# ----------------------------------
# Let's merge that change
# ----------------------------------
cd ..
mkdir tests
cd tests
fossil clone ../main.fossil local.fossil
fossil open local.fossil testing
fossil merge --cherrypick rfc-01
