[PATCH] completion: fix zsh parsing $GIT_PS1_SHOWUPSTREAM

["Thomas via GitGitGadget" <gitgitgadget@gmail.com>]

From: Thomas Queiroz <thomasqueirozb@gmail.com>

Since GIT_PS1_SHOWUPSTREAM is a variable with space separated values and
zsh for loops do no split by space by default, parsing of the options
wasn't actually being done. The `-d' '` is a hacky solution that works
in both bash and zsh. The correct way to do that in zsh would be do use
read -rA and loop over the resulting array but -A isn't defined in bash.
