I guess, this needs to be added for the relevant arguments: https://docs.rs/structopt/0.2.15/structopt/clap/struct.Arg.html#method.allow_hyphen_values

Thanks for merging.

The changelog entry is not correct:

+## v0.6.7
+
+- [Bugfiz](https://github.com/sstadick/hck/issues/44) to allow for `-` character as separators.

Bugfix vs Bugfiz.
The patch fixes also more than just the separators option. -e, -f options can now also start with a dash: e.g. -5,7.

Something like this would be better IMHO:

Bugfix: allow arguments of options to start with a "-".

Yep, you're totally right. Changelog updated as well as releases page
