git-completion.bash: Show list of local branches instead of refs for git checkout

[Amandeep Gautam <amandeepgautam5@xxxxxxxxx>]

Hello,
    I am using git-completion.bash and when I try to checkout a branch
by typing git checkout on the prompt, I get the following:

FETCH_HEAD FETCH ORIG_FETCH

Will it not be more useful if the list of local branches is populated?
If it seems like a good idea I will be willing to submit a patch.

Regards,
Aman
