Following some discussion on -hackers, here's a trial patch that reduces
the amount of space taken by symlinking the git repos on all non-HEAD
branches to the HEAD branch repo.
There are more steps we can possibly take to reduce space consumption,
but this is a start. If anyone is feeling brave they can apply this and
see how it goes.
For now at least, it doesn't work on Windows, nor on machines using the
git_reference config setting.
