>I understand.  On my system I can reproduce this by providing a bad argument to `git merge`.  This is the output from the arg setup.  For "boolean" arguments (like '--ff'), there is an automatic counter argument with "no-" in there ('--no-ff') to disable the option.  Maybe it would make sense to word the output to include both.
