Sometimes when I use git diff I receive

fatal: ambiguous argument 'foo': unknown revision or path not in the working tree.

as an error message. This kind of message could be avoided by using -- to separate commits and files.

What about use -- in the lesson as a good practice? So instead of

$ git diff HEAD mars.txt

we will use

$ git diff HEAD -- mars.txt
