Fix implicit default command starting with unknown option

Reverts to original conditionals structure so that implicitly invoked
default commands behave as if the command name came before the first
arg that is not a known option, and not as if it came before the first
arg that is not an option (known or unknown) like previously.

Fixes pass through and handling of options after the unknown for
implicitly invoked default commands.
