### Expected behavior

When I have a branch name in git like that `my-general-branch-name`. So I expected that modeline will display branch name as is.

### Current behavior

For now, it strips branch name to `my`.

### Steps to reproduce

create git branch, that contains dashes `-`, i.e. `some-branch-name`.
