Kurt b5962d6b50 Emit final showdownset from lines if present
Closes #1986 , was missing a check if there were any lines in the list.
Calling the method with an empty line set would have yielded an empty
set (behavior unknown). Although calling the method without lines is
unintended, should handle behavior correctly now.

Fix yielding an empty set if the first line(s) are empty.

Add test to verify parsing works for multiple lines.
Add test to verify parsing yields nothing for no lines.
Add test to verify parsing yields nothing for empty lines.
