Beman,
the attached patch enables the operator++(int) in directory_iterator.

To summarize our discussion with Dave:
1. New single pass iterator requirements did not meants to outlaw returning 
proxy from operator++(int)
2. Even if proxy is automatically generated by iterator_facade, this might 
take some time to be implemented. In fact, I no longer believe it's really 
desired.

So, implementing operator++(int) is directory_iterator makes sense.
The attached patch basically uncomments your code, adds one using declaration 
to bring preincrement operator++ into the scope and changes the tests.

Okay to commit?
