3) Merge options can't be overridden.
If I modify .git/config to set a merge option, for example forcing
fast-forward merge, this option cannot be overridden on command line:
(git merge --no-ff-only --no-ff) should work. The --no-ff-only overrides
the --ff-only configuration setting, and the --no-ff ensures that the merge
is not a fast-forward.
