The '--geometric=<n>' argument specifies that each pack must contain at least 'n' times as many objects as the size of the next-largest pack. The factor 'n' is customizable, but setting it to '2' is a sane default.
Instead of making the factor a required argument, make the argument optional with a default value of '2'.
To ensure that the option is setup correctly, modify the most complex test of t7703 to drop the explicit factor.
