[boost] [pointee] partially specialize for pointer types?

Right now, boost::pointee<T*> is evaluated to T via evaluation of
boost::detail::is_incrementable<T*>. Unfortunately, this causes a hard
error when T is incomplete. See [1] for motivation on why this might be
undesirable. It seems there's no loss in partially specializing
boost::pointee for pointer types to allow it to be used for incomplete
types. Ditto for boost::indirect_reference. Are there issues with this that
I might be missing?

As both pointee and indirect_reference seem to fall under the purview of
Boost.Iterator, I would take responsibility of making this change and
adding appropriate unit tests for the incomplete type case.
