o plot(phy, root.edge = TRUE) failed if there was no $root.edge in
the tree: the argument is now ignored.
+ o add.scale.bar() failed when 'x' and 'y' were given (thanks to Janet
+ Young for the fix).
+
OTHER CHANGES
o The argument 'adj' in [node][tip][edge]labels() now works when
using 'pie' or 'thermo'.
+ o A more informative message error is now returned by dist.dna() when
+ 'model' is badly specified (partial matching of this argument is
+ done now).
+
o Deprecated functions are now listed in a help page: see
help("ape-defunct") with the quotes.
