+This usually happens to me when I intended to use just `git commit`
+but typed `git commit -a` and committed a whole bunch of more stuff
+that I hadn't mentioned in the commit message.
+
+It's easy to fix just the message for the last commit:
+
+    $ git commit --amend -m "New commit message"
+    
+Or leave off the `-m "New commit message"` and type the message in the
+text editor that opens.
