How to use git-completion on my openSUSE #1

Default repositories of openSUSE don't contain git-completion.bash So I manually integrate it into my openSUSE like below:

1. Download the latest git-completion.bash from here
2. save git-completion.bash in local: e.g. /etc/git-completion.bash
3. In the /etc/bash.bashrc.local, write test -s /etc/git-completion.bash && . /etc/git-completion.bash

Then I can use git completion - git commands, branches, remote sites and so on. to be continued...
