This branch will point to the newly +created parent commit of the branch. If in SVN the branch was deleted +and later recreated from a different version, there will be multiple +such branches with an '@'. + +Note that this may mean that multiple Git commits are created for a +single SVN revision. + +An example: in an SVN repository with a standard +trunk/tags/branches layout, a directory trunk/sub is created in r.100. +In r.200, trunk/sub is branched by copying it to branches/.
