It used to mean to actually include the config file.  This became a broken
meaning when the include directive was added in 2001, if this directory
wass actually used, so that a typical config file looked like:

 	include MOST
 	options 	extra
 	nooptions	noextra

This was fixed in 2007, but at the same time, for some reason stripping
the comments became the default.

Of course GENERIC shouldn't have verbose comments (except meta ones).
Please remove any others :-).  There are only 2 really annoying ones
in the i386 GENERIC:
- one for puc
- a set of 3 separate 1-line extra ones for bpf, the first line of which
   essentially just repeats the expansion of the acronym `bpf' but does it
   with different capitalization.
