   The more I think about this - the more I like this implementation. It 
says - 'if you requested that the command be executed directly by 
explicitly setting JAMBASE to '%' then it should be done so'.

   And as a slight helper - it falls back to using the default shell in 
case the user specified multiple lines since these can not be executed 
directly as-is.

   We might even report this multi-line case as an error or simply 
execute each of the given commands in a loop directly, stopping if any 
of them returns an error and collecting all of their output together...

   Comments welcome...

   Best regards,
