If you are only dumping a single revision, but do not specify
--incremental, then it will put the full text of the repos. With
a branch this will result in a dump of twice the size. With
incremental the previous revision used for the copy that
made the branch will be referenced, so that the lazy
copy will be present and the size will not double.
