Description
When syncing, svnsync first commits the changes from the source repository revision to the destination repository and then copies the revision properties in a second step. If the source repository contains empty revisions, the destination repository will not be an exact copy of the source repository since empty revisions are missing the svn:author revision property. An empty revision will have no author in the source repository and the username svnsnyc uses as the author in the destination repository. If test data is needed, revisions 6192 to 6196 of the svn repository should do the job.
