* docs/html/debug.html: Users are allowed to specialize in
namespace __gnu_debug, unlike in the Apple version of the debug
mode. Clear up a confusing double-negative. Note that
std::basic_string does provide extra debugging capabilities, but
not safe iterators.
* include/bits/basic_string.tcc: Make sure there's never an
ambiguity when calling __is_null_pointer.
* include/debug/deque: (deque::erase) Properly handle invalidation
when erasing at the end of the deque.
* include/debug/vector: (vector::swap): Swap _M_guaranteed_capacity.
(vector::clear): Set the guaranteed capacity to 0.
* testsuite/23_containers/deque/invalidation/4.cc: (test04): Test
iterator invalidation when erasing at the end of the deque.
