setsid: document -w.
-w was added recently. The change in behavior so we now always fork
means that it's needed in more cases too: other implementations of
setsid(1) only fork if getpgrp() != getpid(). This broke a script, which
is what made me notice the missing help.
This seems to have been an accidental change, and is contrary to what
the util-linux setsid(1) man page says: "The command calls fork(2) if
already a process group leader. Otherwise, it executes a program
in the current process", but whether we change our behavior or not, we
should document the new option.
