[feature request] Add configurable feature branch separator #1069
Description
After having been burned a few too many times by the use of / to separate branch parts (it works, but it doesn't necessarily work the way that people think it should unless they're git experts), I have an aversion to this separator being used and do not allow it at the workplace. It would be useful to be able to have a default configuration and/or a flag to be able to specify this value.
git config --get git-extras.feature.separator and/or -s|--separator would be useful from my perspective.
This way I could do git config git-extras.feature.separator - and I would get feature-branchname instead of feature/branchname.
