8ab1155fc5 ENHANCED: use call_residue_vars/2 to show all pending constraints 
Example:

then reverted, and is now restored.

5f1f07e5a1 Add --no-add-history flag 
Flag prevents the input stream from saving terms to ~/.scryer_history
when set. Use the flag when running tests to increase test isolation.
