Call setup_git_directory() early

Any git command that expects to work in a subdirectory of a project, and
that reads the git config files (which is just about all of them) needs to
make sure that it does the "setup_git_directory()" call before it tries to
read the config file.

This means, among other things, that we need to move the call out of
"init_revisions()", and into the caller.

This does the mostly trivial conversion to do that.
