The double negation is very hard to read. I wonder
if ((type != OBJ_TAG) &&
!((type == OBJ_BLOB) && (flags & GPG_VERIFY_BLOB)))
is easier to follow? "It is not a tag object, and it's not like we
were asked to verify blob and the user gave us a blob, either, so
let's complain" is easier to follow, at least for me.
Or even
if ((flags & GPG_VERIFY_BLOB) && (type != OBJ_BLOB))
"you told me to check blob but didn't give me one";
} else if (type != OBJ_TAG)
"you didn't give me a tag";
