There are about 20 similar negative options (one for each normal
option).  They shouldn't be documented explicitly.  Instead, give
the meta-rules.  These are rather complicated and broken.  For most
options "foo", there is a "nofoo" option.  For most options "nofoo",
there is a "nonofoo" option, but it is spelled "foo".  "nonoclusterr"
produces a bogus error message saying that "noclusterr" is not
supported, but it is "nonoclusterr" that is not supported.  For N
extra "no"'s the error message says that the option with N-1 extra
"no"'s is not supported.

The negative options (that don't start out as negative, like noatime)
are only useful in conjunction with the new FreeBSD options -o current
and -o fstab.
