Fix send-pack for non-commitish tags.
Again I left the v2.6.11-tree tag behind. My bad. This commit makes sure that we do not barf when pushing a ref that is a non-commitish tag. You can update a remote ref under the following conditions: * You can always use --force. * Creating a brand new ref is OK. * If the remote ref is exactly the same as what you are pushing, it is OK (nothing is pushed). * You can replace a commitish with another commitish which is a descendant of it, if you can verify the ancestry between them; this and the above means you have to have what you are replacing. * Otherwise you cannot update; you need to use --force.
