+  If a TRANSLATION table is present it is assumed that only the tip

+  logic behind this is that in the vast majority of cases, node labels
+  will be support values rather than proper taxa names. This is
+  consistent with \code{\link{write.nexus}} which translates only the
+  tip labels.

   `read.nexus' tries to represent correctly trees with a badly
   represented root edge (i.e. with an extra pair of parentheses). For
   instance, the tree "((A:1,B:1):10);" will be read like "(A:1,B:1):10;"
