I can't think of a scenario off the top of my head but I'm not saying 
you're wrong. Yes, it's hacky. However, issuing a bad command to TW is 
not some mission critical problem that can't be easily reversed. Doing 
the risk/reward calculus, it seems to have far more upsides than 
potential downs.

I wouldn't recommend this as an official part of the TW release, but 
since this is just a hack for my own use and convenience, I see no harm 
in deploying it.

OK, right.

I have modified PWS' solution to this:

accept-with-quote() {
   if [[ $BUFFER = (tasn|tast|ta|tat|tm|taa|tai|tau|task)' '* && $BUFFER 
!= *\\* ]]; then
       BUFFER=${BUFFER//\'/\\\'}
       BUFFER=${BUFFER//\(/\\\(}
       BUFFER=${BUFFER//\)/\\\)}
       BUFFER=${BUFFER//\&/\\\&}
   fi
}

This doesn't look nearly as elegant as your solution. But I can (mostly) 
understand it and modify it myself, which is probably more important for 
a zsh newb like me.

But huge thanks for your time and input. I enjoying kicking the ball 
around on this stuff. Helps me learn.
