I have a remote branch remote-branch-long-name. When I magit checkout with helm completion I can type remote-branch and origin/remote-branch-long-name will show up as an option. The issue is that to checkout this branch locally, I actually cannot switch to that branch, I need to switch to remote-branch-long-name (without the origin/ prefix), since helm doesn't provide that as a completion option, I have to manually type the entire branch name out.
Is there another function I should be using for this use case or do I have to hack a function together?
