When the PR updating the
subtree/library
branch has been merged already we may still need to bring updates intomain
that haven't previously been added to a pull request. This situation arises when an older merge-into-main PR was still open at the time where the subtree automation creating thesubtree/library
update PR ran.The changes in this PR avoid this problem by making sure the merge-into-main part of the automation is run even when
subtree/library
is already up-to-date.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 and MIT licenses.
