open_key() returns INVALID_HANDLE_VALUE and EACCESS also if an upper
level key cannot be opened. The exists() function returns 1
(virt_directory) then, it should return 0 (virt_none).
write a comment.
I presume this fixed the access-denied-on-last-component case:
"/proc/registry/HKEY_LOCAL_MACHINE/SECURITY" -> filetype = 1 (OK)
but unfortunately then the same info is returned for all ".../SECURITY/*".
But what you say sounds right to me. Please create a patch.
I'll try next week. A fix likely needs to enhance open_key() such that
it returns info whether the access was denied on last component or not.
