[PATCH] Apply DR235 correctly: reverse_iterator default ctor.

[Nathan Myers]

This one is pretty clear if you read the resolution of DR235 and the 
definitions of the terms involved.

	* include/bits/stl_iterator.h (reverse_iterator::reverse_iterator()):
	Apply DR235: default constructor default-initializes data member.
	Instantiated on a pointer type, the member has to end up equal
	to zero.
