drop rand dependency, rewrite tests and fix skip_current_dir panic #125

Closed BurntSushi closed 4 years ago

This PR includes some refactoring I did a while ago to prep for a bigger change that I haven't had time to finish yet, so this splits out the refactoring into its own set of commits. Notably, this drops the rand dev dependency and re-enables the minimal version check.

This also rolls up #124, which fixes #118.
