Add the new Args / entry-access API.

The long-term goal here is to get rid of the functions
GetArgumentAtIndex() and GetQuoteCharAtIndex(), instead
replacing them with operator based access and range-based for
enumeration.  There are a lot of callsites, though, so the
changes will be done incrementally, starting with this one.
