Graham,
"special Preparation" of say 1.0 mm2 or whatever , would you be inclined to put a cable doubled doubled doubled ......... etc into that category? In an ideal world (which does not actually exist) such doubling (or twisting if you must) will take the conductor effective diameter up towards the terminal hole diameter thus making decent electrical contact and possibly mechanical soundness too.
Doubling back may be OK as "preparation" for screw terminals, if you can effectively fasten down on both sides - more than a simple doubling back (double-double) I'm thinking might well fall into the "too hard" or "bit of a bodge" category.
But of course, screwless terminals and crimp connectors are another thing altogether and you should follow manufacturer's instructions for those.
