wrong error msg

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

Probably not worth reporting but:

    echo "Restore \"${previous?\"? (y/n)"

in a script reports: " unmatched " " whereas it should be an unmatched 
curly where the first question mark mistakenly is . Mind, it's quite 
something how the parser usually figures these things out, and sometimes 
it must be a judgment call trying to discern one's intentions.
