[9fans] bug in rc(1) ?

[arisawa]

rc(1) says:

          rfork [nNeEsfFm]
               Become a new process group using rfork(flags) where
               flags is composed of the bitwise OR of the rfork flags
               specified by the option letters (see fork(2)). If no
               flags are given, they default to ens.  The flags and
               their meanings are: n is RFNAMEG; N is RFCNAMEG; e is
               RFENVG; E is RFCENVG; s is RFNOTEG; f is RFFDG; F is
               RFCFDG; and m is RFNOMNT.

this sounds to me
        rfork
is equivalent to
        rfork ens

or am I misunderstanding?
