Well I'll be....

I never noticed it before, but it sure is there.  -  I guess that means 
that I won't mind it henceforth either.  :-)

Ya, I was doing that during my diagnostics.

My goal is to overload space so that I don't need to hit special keys.  ;-)

You've gotten me a LOT closer.  And some brute force hacking (less than 
gracefully) got me to what I think I want.

maybe-expand-or-complete() {
	if [[ $LBUFFER[-1] != ' ' && -z "$JUSTCOMPLETED" ]]; then
		zle expand-or-complete
		if [[ $LBUFFER[-1] != ' ' ]]; then
			JUSTCOMPLETED=true
		fi
	else
		unset JUSTCOMPLETED
		zle self-insert
	fi
}
zle -N maybe-expand-or-complete
bindkey ' ' maybe-expand-or-complete
setopt recexact

The key was to retain state between maybe-expand-or-complete() 
executions via JUSTCOMPLETED so as to not call expand-or-complete 
successively when there were multiple matches.

Thanks to your help Daniel, I believe I have something that I can start 
using and deal with any annoyances as they come up.  :-)
