Nice finding. How did you discover this issue? Did you use a tool to find 
this ununsed code or stumble over it during your code review?

Also note that commits are referred to with this format:

commit <12-character sha prefix> ("<commit message>")

So, you need to change patch to commit and include brackets around your
quoted commit message.
