#5124: Improve documentation for Data.Traversable.fmapDefault

---------------------------------+------------------------------------------
Data.Traversable.fmapDefault in fact only works with Traversable instances
which override the definition of traverse, not with instances which only
override sequenceA (although such instances are perfectly valid). I've
attached a patch noting this in the fmapDefault documentation.
