When reading the synopsis for git-for-each-ref it is easy to miss
the obvious power of --shell and family. Call this feature out in
the primary paragragh. Also add more description to the examples
to indicate which features we are demonstrating. Finally add a
very simple eval based example in addition to the very complex one
to give a gentler introduction.

This adds a new command, git-for-each-ref. You can have it iterate
over refs and have it output various aspects of the objects they
refer to.
