Description

From version 1.13.0, the configuration [repository.pull-request] DEFAULT_MERGE_MESSAGE_ALL_AUTHORS, used as default (false), is not being honoured in a squash commit type of PR.
I just want the commit title in the commit message, as in the earlier versions. Cleaning the message with the Co-Authored-By lines doesn't work, these are appended again to squash commit message.

DEFAULT_MERGE_MESSAGE_ALL_AUTHORS=false means only collect authors for the DEFAULT_MERGE_MESSAGE_COMMITS_LIMIT.

Sorry, my bad. Probably the new behaviour has no connection with the configuration.
But from 1.13.0 version the message about Co-Authors is being appended automatically.

I am amending my commits to get the title only, as in previous 1.12 versions when no message was inserted.

@zeripath
Reading your post at #15914 (comment) i thought that the body of the squash merge message would be removed with the new setting.
In 1.15, are there any way to achieve a single message in a squash merge?
Is a lot boring do a force push after every PR merge. And branch protection needs to be disabled to do that.

Fixed in v1.16.0 by PR #17848.
