Support multiple lines in directory COMPOPTS
Support multiple lines in directory COMPOPTS

Multiple lines here are only supported if .compopts is not provided.
If multiple lines are provided, COMPOPTS will be ignored when
the .compopts are processed.

I need this functionality to simplify some tests I'm adding for
record construction/assignment/destruction.
