[volt-nuts] Banana jack shorting straps

[Randy Evans]

I believe that the Fluke shorting system has 3/4" spacing both vertically
and horizontally, which is not compatible with the 3458 (I couldn't find a
spec but visually it looks identically in both dimensions in the photos).
The 3458 spacing is slightly greater than 3/4' horizontally.
