If the answer is "the visual lines prompt negates the need to set the value", 
then 
this is me giving a *groan* :)

I read and understood how that worked, I just didn't think a buffer-local 
changing
of the value to double the current troublesome line was the same as changing 
the value globally and deliberately to a number that specifically works for 
the user.

Even if it was a bit of a snipe hunt, I learned a bunch in the process! :P
