Git completion on a branch when doing a force push

[rocketraman]

When doing git completion, fish generally completes the branch name e.g.

git push origin <completion here>

However, when doing a force push with a +, the branch completion does not work:

git push origin +<no completion here>

Fish version: 2.2.0

Operating system: Fedora Linux

Terminal or terminal emulator: Konsole

Yes, this needs to be implemented.

When it is, this should not recommend all branches with a "+", but only complete branches even after a "+" and maybe give a standalone "+" with a description of "force push" or something. Everything else would cause way too many options, about half of them dangerous.
