Re: suggestion for a simple addition: git update-ref --ff-only

Hi list,

I'd like to suggest a very simple, but IMHO quite useful, additional
option to git-update-ref: an option --ff-only which would cause the
command to refuse unless the current ref is an ancestor of the new

Mild NAK.

What you want may be "git push . new_commit:refs/heads/foo", by the
way.

The "update-ref" plumbing does not want any such frill.
