In what different contexts does this get called, I wonder?

I think

	$ git cherry-pick --cleanup=bogus ...

should error out, instead of falling back to anything else, while
having

	[commit] cleanup = bogus

in .git/config should *not* say anything if you are not running a
command that does not get affected by the commit.cleanup variable,
and with such a bogus configuration, a command that does use the
variable should either also die, or fallback with a warning.

I have a suspicion that the change is breaking the error detection
done for the command line argument parsing, and if that is the case,
then it is a bad idea.  But I may have misread the code.

Thanks.
