As I was saying, my whole zsh universe revolves around it.  Might have been
a mistake at the getgo.  Still, every problem has been solved one way or
another and it's me trying to make the shell do what it doesn't want to do
so if it isn't easy that's my problem.

(q) gets close to my philosophical instinct of how the thing should 
work.  But if
there was some way of providing a string with absolute protection then I 
could
proceed naively -- the string is always going to be exactly as I typed 
it.  Nevermind
tho, my functions work 90% as close to my theoretical model as I could want.
Remaining issues are whiny not substantive.
