Latest commit da901da Oct 17, 2017 @Zarel Zarel committed with ScottFreeCode Make sure `mocha -h` consistently shows help (#2746)
* Make sure `mocha -h` consistently shows help

Previously, having options in `test/mocha.opts` would add those to `process.argv` to be passed to `program.parse`, which would make it stop showing help.

Fixes #2745
