Description
Per http://svn.haxx.se/dev/archive-2008-10/0280.shtml, svnmerge-migrate-history.py (and probably svnmerge-migrate-history-remotely.py, too) do not ensure that the svn:mergeinfo properties they create have their rangelists sorted properly, which can result in the versioning of bogus property value that Subversion can't use.
