Change option lists to be specified as separate arguments on commands line

Option lists and maps are specified using separate arguments, avoiding
the need for additional escaping of their separator and reusing the
existing command line spliting logic instead.

As discussed on #2087, this should make it much easier to work with
list options, and make the general option system feel cleaner.
