According to Lennard it's "an irritatingly common occurrence".

Maybe if they used special Campagnolo non-stretch shifter cables it

Mr Zinn's right on that point.

Campagnolo Ergo wires stick one's palm as they start to fray, well

Which version/models/years are you referring to? I rode Campagnolo Chorus 9Sp for many years, never had that experience.

The wire path is on the outside and the capstan spools under the lever, so fraying starts at the outside bottom of your palm and although not painful it's noticeable.

 Is that on the older 9sp stuff as well?
 

Yes, all 8, 9, 10 Ergos from 1992; same wire path.
The 11, 12, 13 speed (non rebuildable) Ergos have the same general layout but the wire path is under a cover so now a fraying wire won't stab the operator.  A broken head still falls straight down, out of the shifter, rather than mangling the mechanism as with The Other brand.
