What do you think is missing?

RRDtool needs to see '*', not '\*' or alike.

Evaluating '*' into something else, and thus the need to escape that 
behaviour in this case, is a property of your shell, not of RRDtool. You 
could write the entire statement like so: 'CDEF:kmh=nonans,3600,*'
and the shell won't expand '*'.

Nevertheless: thanks for carefully reading the tutorial, and keep hunting 
minor nits, as I'm sure there are real ones in it ;)
