Re: Git in a Nutshell guide

A few comments (from what I checked so far):

1. It is "man git-checkout" (or "git checkout --help"),
   not "man git checkout"

2. Instead of using 'verbatim' environment directly to show example CLI
   session it would be I think better to define verbatim-like environment
   for this ('example', 'commands', 'CLI', 'session'); perhaps replacing
   verbatim by lstlisting from the listings/lstlisting package for syntax
   highlighting.

I'll send more comments after reading it in full...
