Explicitly use 'exit 1' to exit
Fixes #286 Using `exit $?` will exit with 0 status even in error conditions. I believe this is due to the fact that the `if` statement sets `$?` somehow. This could be a bug in the version of `bash` I'm using (as `/bin/sh`): ``` $ /bin/sh --version GNU bash, version 4.3.30(1)-release (x86_64-unknown-linux-gnu) ```
