class directory_entry should retain operator const path&() from V2.

[2014-05-19 Beman Dawes supplied proposed wording.]

[2014-06-02 Beman Dawes provides rationale:]

This conversion operator was removed when status() and symlink_status() were added during the transition from V2 to V3 as it seemed a bit unusual to have a conversion operator for one of the several values held. Users complained as they had found the automatic conversion convenient in the most common directory_entry use case.

[17 Jun 2014 Rapperswil LWG discusses in depth, accepts proposed wording.]

Proposed resolution:

Change 12 Class directory_entry [class.directory_entry]:

// observers
const path&  path() const noexcept;
operator const path&() const noexcept;
file_status  status() const;
file_status  status(error_code& ec) const noexcept;
file_status  symlink_status() const;
file_status  symlink_status(error_code& ec) const noexcept;

Change 12.3 directory_entry observers [directory_entry.obs]:

const path& path() const noexcept;
operator const path&() const noexcept;

Returns: m_path
