f0562504b7 Exclude deprecated fn from mutation testing (Jamil Lambert, PhD)
4d31b141a8 Improve is_too_precise test (Jamil Lambert, PhD)
a2bae3bb0b Add test for impl Display for Script (Jamil Lambert, PhD)
Pull request description:
Weekly mutation testing found new mutants. There are also some untested mutants in match statements that will be included in future mutation testing once #4654 goes in.
- Add a regression test for the mutants in the `Display` impl for `Script`.
- Improve the existing test for `is_too_precise` to check all four cases.
- Exclude the two deprecated functions that have untested mutants.
Closes#4646
