+to reset the HEAD to another commit (`target`) with the different

+In these tables, A, B, C and D are some different states of a
+file. For example, the last line of the last table means that if a
+file is in state B in the working tree and the index, and in a
+different state C in HEAD and in the target, then "git reset
+--merge target" will put the file in state C in the working tree,
+in the index and in HEAD.
+
+The following tables show what happens when there are unmerged
+entries:
+
+      working index HEAD target         working index HEAD
