transform_iterator documentation ignores operator->

[eelis]

In the transform_iterator documentation, the "abstract"
section states that "The transform iterator adapts an
iterator by modifying the operator* to apply a function
object to the result of dereferencing the iterator and
returning the result.". It seems a bit strange to me to
mention operator* but not operator->, which is modified
in the exact same way.

Then, in the "synopsis" section, operator* is listed
but operator-> is not, even though it is definitely
part of the interface (otherwise transform_iterator
cannot model the concepts that it claims to model in
the "models" section on the same page).

The abstract is an abstract; it doesn't need to describe
every detail.  The idea is that you can understand what the
component does.  I agree that the synopsis should probably
list operator->.  Doc patches gratefully accepted.
