If you set it up with these settings then the disk space used is minimal:
git_use_workdirs => 1,
rm_worktrees => 1,
So I have this on crake:
andrew@emma:root $ du -sh REL*/pgsql
5.5M REL_10_STABLE/pgsql
5.6M REL_11_STABLE/pgsql
5.6M REL_12_STABLE/pgsql
5.6M REL_13_STABLE/pgsql
2.0M REL_14_STABLE/pgsql
2.6M REL9_5_STABLE/pgsql
5.5M REL9_6_STABLE/pgsql
cheers
