subrepo: create subrepos using clone instead of pull Subrepositories used to be created empty and then filled with data using pull. This is wasteful when you do a clone from a local source since it means that no hardlinks are created for the subrepos. This patch make the hgsubrepo._get method check for an empty subrepo and in that case do a clone instead of a pull. This brings in the same data as before, but creates hardlinks when possible.
