There is a bit more serious issue than coding, actually.

Short options.

A script wants to use default rename detection threshold for unknown
commit $foo whose name might look like a number.  IOW, this

	git diff -M $foo

could be ambiguous.  Obviously, "git diff -M-default $foo" would not fly
very well.
