+You can get interrupted by an ungent fix request while you are

+    your working tree in the state just before you made that snapshot.
+<3> After <2>, the index file still has all the WIP changes you
+    committed in <1>.  This sets it to the last commit you were

-* For backward compatibility, `tag` is almost ignored;
