6734	Default argument for transform_iterator constructor	philipp.moeller@…	Dave Abrahams	"The current non-default constructor version of transform_iterator is:

  transform_iterator(Iterator const& x, UnaryFunc f)

this should be 

  transform_iterator(Iterator const& x, UnaryFunc f = UnaryFunc())

for better usability. Sometimes it is also not possible to know or
extract the function that was used to define the transform_iterator
easily, because there is no typedef for it inside transform_iterator.
