Git merge doesn't use default merge message, opens editor with default message

Question

How can I force git merge to use the default merge message instead of loading my editor with said message?

I have no editor listed in git config -l, so I'm not sure why it opens an editor.

Found the answer after some digging

EDIT: As per Mark's suggestion, this is the best way to do so:

git config --global core.mergeoptions --no-edit
