Perhaps it would be a useful feature to report the other two things, too.

yash does exactly that:

$ yash -c 'echo "Restore \"${previous?\"? (y/n)"'
yash -c:1: syntax error: the double quotation is not closed
yash -c:1: syntax error: `}' is missing
yash -c:1: syntax error: the double quotation is not closed

Would this be difficult to implement in zsh?
