There was a problem hiding this comment.

Refactored as you suggested. The error code is the same as what have been used elsewhere in the file; is there some sort of standard? |

…lacrum libtest: Replace panics with error messages This replaces explicit panics on failures in libtest with prints to stderr. Where "failures" == CLI argument parsing and such Before: ``` $ ./foo-stable --not-an-option thread 'main' panicked at '"Unrecognized option: \'not-an-option\'"', libtest/lib.rs:251:27 note: Run with `RUST_BACKTRACE=1` for a backtrace. ``` After: ``` $ ./foo-nightly --not-an-option error: Unrecognized option: 'not-an-option' ```
