contrib/solaris/opensshd.in patch

[Rob Mallory]

Hmmm.. you are right. Dunno what I omitted when 
cut n pasted your (nice and unbloated) version.
...and yes, I do want to kill the one who $ppid=1, 
{was stuck in thinking ass-backwards like my example}
yeppers.....
   anyways, I hope people agree this'd be nice to have
in the tree..... it saved my butt a few times in the past...

Did you try it?  it seems to kill all sshd's here.
specificaly, you (or at least I)_don't_ want to kill anything where $2=="1"
from the ps -opid,ppid,fname line to be killed.
 
also I don't want to kill parents of any procs called "opensshd"
which is the name of the script.

Here's a bit simpler change that accomplishes the same task:
