Ole - Can you possibly provide examples of how changing the quoting engine might change how parallel is invoked?
Or is the intention that there is no change?

A job can be a single command or a small script > that has to be run for each of the lines in the input. The typical > input is a list of files, a list of hosts, a list of users, a list of > URLs, or a list of tables. A job can also be a command that reads from > a pipe.
