[PATCH] git-completion.bash: replace zsh notation that breaks bash 3.X

When commit d8b45314 began separating the zsh completion from the bash
completion, it introduced a zsh completion "bridge" section into the bash
completion script for zsh users to use until they migrated to the zsh
script.  The zsh '+=()' append-to-array notation prevents bash 3.00.15 on
CentOS 4.x from loading the completion script and breaks test 9902.  We can
easily work around this by using standard Bash array notation.
