From 191d9b2356fea1bb7b610056bdc3076c4f8a61d2 Mon Sep 17 00:00:00 2001

Subject: Read bz.* git config upfront

Instead of making calls to git.config() as needed, read all of our options
ahead of time into a dictionary initialized with defaults.

Loosely based on a patch from Felipe Contreras <felipe.contreras@gmail.com>.
