how to make git checkout <tab> show only the branches I have locally

Question

When I want to check a branch to checkout to and I don't remember the exact name, I can't use Tab-completion, as the pool it uses is the branch pool of remote.

How can I make the Tab only look at the git branch pool (i.e. only choose from the local branches I created / already checkedout)

Answer 1

One way is to modify the standard code completion script for git checkout, example (& credit) below:
