Comment #8 on issue 15 by cmpilato: Examples should make more accurate use  
of peg/working revisions

Only Chapter 9 (the Reference) remains to be reviewed for peg revision  
usage now.

Unfortunately, since most of the book deals with working copy targets, peg  
revisions really don't get much time in the spotlight.
