Teach 'git merge' and 'git pull' the option --ff-only
For convenience in scripts and aliases, add the option --ff-only to only allow fast-forwards (and up-to-date, despite the name). Disallow combining --ff-only and --no-ff, since they flatly contradict each other. Allow all other options to be combined with --ff-only (i.e. do not add any code to handle them specially), including the following options: * --strategy (one or more): As long as the chosen merge strategy results in up-to-date or fast-forward, the command will succeed. * --squash: I cannot imagine why anyone would want to squash commits only if fast-forward is possible, but I also see no reason why it should not be allowed. * --message: The message will always be ignored, but I see no need to explicitly disallow providing a redundant message. Acknowledgements: I did look at Yuval Kogman's earlier patch (107768 in gmane), mainly as shortcut to find my way in the code, but I did not copy anything directly.
