You could use the --ignore-ancestry option but because this disables merge
tracking you'll also either need to specify one or more revisions to merge,
or use the 2-URL merge syntax. See 'svn help merge' for more details.
For the long term, I would recommend to reconcile the branches, then delete
one of the branches and recreate it as a copy of the other.
