config: use NUL-delimited git-config(1) output

This allows us to deal with newlines in config values,
since git-config(1) acquired "-z" support in git v1.5.3.

I'm not sure if it's actually useful in our case, but
maybe some multi-line texts could be added.  And newlines
in path names are super useful!
