From: Andreas Schulz <ats@g386bsd.first.gmd.de>

1) getpgrp used inconsistently. The kernel module is changed to
the new POSIX getpgrp without a parameter. But sys/kern/init_sysent.c
and also sys/kern/syscalls.master lists it with one parameter, and the
man page under src/lib/libc/sys/getpgrp.2 is also the old one. The include
file src/include/unistd.h looks like the new definition.

(Brought in man page from NetBSD, which had been updated to reflect this
change)
