Put local var declaration in its own line in lib/git.zsh

Browse source 
In places, the local statement will override the exit code and the written
command won't have the effect intended when it was written.

For example, when it's not inside a git repo the exit code won't be true,
but the local statement will make it true regardless. See #4708.
