subrepo: lazily update git's local tracking branches
This continues the strategy of separation between hg pull and hg update in
git subrepos by only dealing with git's branches on an update. This behavior
tries to cover the bare essentials of the semantics of git pull in the subrepo
when the parent repo does hg pull and hg update.

SVN wants all paths to start with a slash. Unfortunately, Windows ones
don't. Handle that.
