All of your questions is about !origin vs !*origin.  This applies to
the code in 'master', not specific to jc/attr topic's improvements.
It is how the prepare_attr_stack() tells where the .gitattributes
for the top-level directory is when popping the elements for other
directory hierarchy we have left (origin && !*origin is the root
level). !origin denotes entries that did not come from in-tree files
(i.e. $GIT_DIR/info/attributes, built-in ones, etc.).
