There's more than one reason why ssh would ask for a password. So just
checking for an encrypted key is pointless. Instead, ssh could be 
invoked with -o BatchMode=yes. ls-remote could pass this option if it 
was invoked with --quiet.

Possible this is just not worth the trouble and Hong should enter the 
run ssh-agent and enter the password beforehand.
