So fetching tags which the client\ndoes not have the objects for, and which the client isn't 100%\nsure it will need to fetch have to be done during the second pass,\nwhich is when the second From line is displayed.\n\nThese tags caught during the second pass are tags pointing at much\nolder commits; commits which no active branch is currently pointing\nat directly, but which are reachable indirectly. That is why you\nare seeing this second pass pick up the \"older\" tags.\n\n-- \nShawn.\n"}]}
