Subject: [PATCH] Fix incorrect comment about std::auto_ptr
Authentication-results: sourceware.org; auth=none

Pedro pointed out this comment isn't true, see LWG 463 for the reason
why (in short, it needs too many user-defined conversions).

	* include/backward/auto_ptr.h (dauto_ptr): Correct comment about
	conversions from auto_ptr<Derived> rvalues to auto_ptr<Base>.
	* testsuite/20_util/auto_ptr/assign_neg.cc: Remove redundant dg-error
	directives that only match notes, not errors.

Tested powerpc64le-linux, committed to trunk.
