Guidebook.txt: silence groff complaints about CR

Browse Source 
Don't attempt to switch to CR font (used to get fixed-width characters
when generating output that uses proportional width ones) when output
is already fixed-width (plain text).

The most recent release of groff (version 1.23) complains when a font
can't be found, then keeps going.  Earlier versions just silently kept
going.  Failing to load the CR font when already producing fixed-width
chars makes 'keep going' acceptable but the font-load-failure warnings
are a nuisance.
