This is similar in spirit to to "make -C dir ..." and "tar -C dir ...".

Often I find myself needing to find out quickly the status of a repository that
is not in my currenct working directory, like this:
$ (cd ~/foo; git log -1)
With this patch now i can simply do:
$ git -C ~/.zsh log -1
That's just one example. I think those who are familiar with the -C arguments
to "make" and "tar" commands would get the "handiness" of having this option in
git.
