Checking out any git branch with vim-fugitive

Whenever I'm in neovim and I want to go back to an old git branch or commit, I normally want to find it first with a :Git log command.

Something like:

:Git log --graph --oneline --decorate --all

would result in this type of output.

I can then scroll to the commit I want to check out and then type coo.

coo checks out the selected commit, and should work on any line that references a commit in fugitive buffer.
